Mk/bsd.port.mk: Add __MAKE_CONF=${NONEXISTENT} to WRK_ENV

And remove it from individual ports.  Use WRK_ENV in custom build
commands where necessary.

FreeBSD make(1) includes /usr/share/mk/sys.mk and that includes
/etc/make.conf if it exists.  This happens when you run make in a port
directory but it also happens when the upstream build system uses make.
This commit disables make.conf inclusion in the latter case because
users can define variables like CFLAGS in make.conf that override ports
framework variables and this can cause problems that are difficult to
diagnose.

If there are any build customisations made through make.conf that stop
working because of this commit then they should be made available by the

*: Bump PORTREVISIONs for math/mpc update to 1.3.1

One more small cleanup, forgotten yesterday.
Reported by:	lwhsu

Remove # $FreeBSD$ from Makefiles.

Update to MPC version 1.2.0 with the following changes:
 - New functions:
   . mpc_sum
   . mpc_dot
 - Several functions are more robust with a reduced exponent range
   (for example corresponding to IEEE 754 binary formats).
 - New mpcheck tool for comparison with the native C library (which
   is not installed by default).

Bump all directly dependent ports. Do not bump those indirectly
dependent via the lang/gcc* family since their run-time dependencies
and code generated should not be affected.

Fix build with src r354909 applied.

The referenced change made NO_INSTALLLIB, NO_MAN, and NO_PROFILE into
errors causing these ports that declare them and use the FreeBSD make
infrastructure as part of their build to fail.

When the offending variables occur in a BSD Makefile, NO_MAN becomes
MAN= and NO_INSTALLLIB and NO_PROFILE become MK_INSTALLLIB=no and
MK_PROFILE=no respectively.  When declared in the environment they
become WITHOUT_<FOO>.

math/libmissing: back out r477151

Bump PORTREVISIONs of all users of math/mpc that we just updated to
version 1.1.0 (via revision 464079).

- Remove always-true/false conditions after FreeBSD 9, 10.1, 10.2 EOL
- Switch to new test framework
- Whitespace fixes
- Switch to options helpers

Reset ports maintained by bf@ until he has time again to work on them.

Remove ${PORTSDIR}/ from dependencies, categories m, n, o, and p.

Repair instances, almost all courtesy of bf ;-), of spaces
and/or tabs before the =. This made doing regular expressions
on the ports tree really difficult.

Support stage
Modernize

Convert all :U to :tu and :L to :tl

Since FreeBSD 8.4 and FreeBSD 9.1 make(1) do support :tu and :tl as a
replacement for :U and :L (which has been marked as deprecated)

bmake which is the default on FreeBSD 10+ only support by default
:tu/:tl a hack has been added at the time to support :U and :L to ease
migration. This hack is now not necessary anymore

Note that this makes the ports tree incompatible with make(1) from
FreeBSD 8.3 or earlier

Update to libmpc version 1.0.1 which brings the following fixes:

 - Switched to automake 1.11.6, see CVE-2012-3386.
 - #14669: Fixed extraction of CC from gmp.h.
 - Fixed case of intermediate zero real or imaginary part in mpc_fma,
   found by hydra with GMP_CHECK_RANDOMIZE=1346362345.

This is on top of the following changes from version 1.0

 - Licence change towards LGPLv3+ for the code and GFDLv1.3+ (with no
   invariant sections) for the documentation.
 - 100% of all lines are covered by tests
 - Renamed functions
   . mpc_mul_2exp to mpc_mul_2ui
   . mpc_div_2exp to mpc_div_2ui

Add NO_STAGE all over the place in preparation for the staging support (cat:
math)

Update math/libmissing to 20130815, and adjust a dependent port

trim headers; switch to the new options format; fix builds after src r248751;
update math/lrng to 20130314, and switch it to a versioned DIST_SUBDIR

simplify and correct precisions; use libm on architectures where long
doubles aren't wider than doubles; reduce the number of mpc/mpfr
variables in some functions; add (l)lrintl, remquol, logbl; minor
cleanup

Add libmissing , standard math functions missing from the FreeBSD libm.
