[OE-core] [PATCH 1/1] archiver.bbclass: Fix archiver for gcc packages using patched sources

[Alejandro Hernandez]

gcc packages use a shared source directory, this causes an issue since
the archiver will try to patch the same source several times (one for
each gcc package), producing an error, the archiver class used stamp-base
to check this, nonetheless our gcc packages no longer use stamp-base,
they use gcc-shared instead, which is what broke this functionality
this patch adds a check to see whether or not the source should be patched,
avoiding patching the source when it shouldnt.
