Divorce the ARM bare-metal GCC ports from the FreeBSD GCC xtoolchain ports.

In the past, changes to the FreeBSD GCC xtoolchain ports have broken
the ARM bare-metal GCC ports by accident.  In addition, we'd like to
move to having multiple FreeBSD GCC xtoolchain ports for different GCC
versions.  It seems best if we make the two groups of ports
independent so that changes to one do not affect the other.

Override the library search directories for external GCC toolchains.

The default library search directories when building a native GCC end
up falling back to /usr/local/lib (for devel/*-gcc) and /usr/lib (for
base/gcc) even when --sysroot is used.  For devel/*-gcc, I previously
forced CROSS_DIRECTORY_STRUCTURE on in r466699 to workaround this.
However, this solution could not be used for base/gcc.  Instead, patch
the sources to remove several of the library search directories and
override STARTFILE_PREFIX_SPEC to only look in /usr/lib.  GCC still
adds tuple-specific subdirs to /usr/lib, but this is ok.

Bump PORTREVISION for both the external GCC toolchains and base/gcc.
