gcc-target.inc: Prevent sysroot from leaking into configargs.h
Prevent the full recipe-sysroot path from leaking into configargs.h. The
configargs.h header is intended to be static and unchanged as the
content is used as a means of determining that a gcc plugin is built for
the same gcc. This also effects the output of 'gcc -v'. Due to per
recipe sysroots and staging, the sysroot path would be replaced with the
sysroot local to the recipe thus changing the content of configargs.h.
This change also improves gcc binary reproducibility. The sysroot path
is replaced with the base target root "/".
