gcc: Support only the latest branch releases of gcc

This change, as per #222, reduces the number of supported releases of
gcc to the latest branch releases.

I noticed while doing this work that gcc-4.5.4 was never added, so I
moved patches for gcc-4.5.3 to 4.5.4 and updated the
bfin-unknown-linux-uclibc example. Also, 120-siginfo.patch was fixed
upstream in the 4.5.4 release, so this patch is omitted.

I also bumped the avr sample to 4.9.3 from 4.9.2.

With the addition of gcc-5.x, the gcc release team now releases the
major.minor.0 versions, while updates to the branch are available in
svn/git. We'll address that when we get to issue #219. This change just
removes CC_GCC_5_1 and moves CC_GCC_5_2 to CC_GCC_5, and removes
CC_GCC_5_1_or_later and moves CC_GCC_5_2_or_later to CC_GCC_5_or_later.

This is the first of two part changes, as mentioned in #222.
This change is slated for release in 1.22.0. The next change will be
slated for 1.23.0, and will limit gcc versions to what is on
https://gcc.gnu.org under "Release Series and Status", which is
currently 4.9.3 and 5.2.0, although I will also support the previous
supported version. In this example that would be 4.8.5.

Last, but not least, this change also retires AVR32 support.

-On glibc the libc.so carries a copy of the math function copysignl() but
-on uClibc math functions like copysignl() live in libm. Since libgcc_s
-contains unresolved symbols, any attempt to link against libgcc_s
-without explicitely specifying -lm fails, resulting in a broken
-bootstrap of the compiler.
