Fixes #8212. See commit message for details.
This simply wraps gcc/g++ rather than requiring a new descriptor.
C_INCLUDE_PATH and CPLUS_INCLUDE_PATH work globally as though -isystem was used
for each invocation.
Since that changes the build results, force a rebuild of x86 depends by adding
the value to $HOST_ID_SALT.
Nice workaround. utACK, going to test
