cc/gcc: remove 'sub-level' version form symbols

Now we use defconfig files to store the samples, we have to be a bit more
conservatives in the symbols names, so as to avoid gigantic version bumps
when updating sub-level versions from a package.

For example (using fictitious versions):
- in crosstool-NG 1.17.0, we choose:
- latest gcc is gcc-linaro-4.7-2012.10, which is the default for the
choice in the menuconfig
- gcc-linaro-4.6-2012.10 is selected
- so, sample has an explicit symbol for the selected gcc version, as it
is not the default
- we update to crosstool-NG 1.18.0:
- latest gcc version is gcc-linaro-4.7-2013.01
- gcc-linaro-46 has been updated to gcc-linaro-4.6-2013.01
- as the sample now has no *valid* symbol to set the gcc version, the
default is used, while we would have expected to still use the 4.6
release from linaro, not the 4.7

Get rid of sub-level (ie. the third digit sequence in versions) from the
symbols for linaro versions.

Hi Robert,

I've attached two patches:
yann@402
    12
yann@402
    13
1/  For crosstool-0.31 which changes the CYGWIN_URL to one which has the
yann@402
    14
cygwin source archives.  The version of cygwin that is used to build the
yann@402
    15
cross toolchain has been changed to cygwin-1.5.15-1-src.tar.bz2 since
yann@402
    16
most of the mirror sites don't seem to have the original archive used.

2/ The later cygwin source archive fails to cross build with the error:
