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.

    30       gdbserver >= 7.2 comes with an optional library to use tracepoints,

    31       the In Process Agent (IPA) library, libinproctrace.so.

    32       

    33       Say 'y' if you indend to use tracepoints when debugging your

    34       programs with gdbserver.

    35       

    36       Note: Currently, building this library is not possible when the

    37             gdbserver is built statically. This is a limitation in

    38             crosstool-NG, so do not bug upstream about it...
