gcc/gcc-initial: fix build of the AVR32 toolchain 

Since we switched to a two stage gcc build process, the AVR32
toolchain stopped building. This is because with such an old gcc
version, we cannot use the all-target-libgcc and install-target-libgcc
targets.

Before the two stage gcc, libgcc was only built in gcc-intermediate,
which carried a similar logic. This commit basically restores in
gcc-initial the logic that used to be in gcc-intermediate, which
consists in using the all-target-libcc and install-target-libgcc
targets only for gcc versions others than the AVR32 one.

Using the BR2_GCC_SUPPORTS_FINEGRAINEDMTUNE option has a way of
distinguishing the old AVR32 compiler from the other gcc versions is a
bit ugly, but it's what was done in gcc-intermediate before. And since
the AVR32 support is due to go away at some point in the hopefully
near future, we don't care that much.

This will fix the build of the two AVR32 defconfig that have been
constantly failing since switching to the two stage gcc process.
