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.

      In case you have trouble with dynamic loading of shared libraries,
yann@175
    23
      you will find that a static gdbserver comes in handy.

      gdbserver >= 7.2 comes with an optional library to use tracepoints,
yann@2986
    31
      the In Process Agent (IPA) library, libinproctrace.so.

      Say 'y' if you indend to use tracepoints when debugging your
yann@2986
    34
      programs with gdbserver.

      Note: Currently, building this library is not possible when the
yann@2986
    37
            gdbserver is built statically. This is a limitation in
yann@2986
    38
            crosstool-NG, so do not bug upstream about it...
