Define GPLv3RLE license (GPLv3 Runtime Library Exception)

The GCC ports either do not have any license defined, or they are defined
as GPLv3 which is not completely correct.  The runtime libraries in the
FSF-issued GCC releases have a standard exception to the GPLv3 license.
In order to properly reflect this, the GCC ports can define a "multi"
license, GPLv3 and GPLv3RLE, which are both in effect.
