[OE-core] [PATCH 4/7] gcc-sanitizers: check gcc-build-internal before link

[Robert Yang]

The ${STAGING_INCDIR_NATIVE}/gcc-build-internal-$mtarget may not exist
when use the external sdk toolchain, we need check before link for it.

Fixed:
run.do_configure.12538: 149: cd: can't cd to sysroots/x86_64-linux/usr/include/gcc-build-internal-x86_64-wrs-linux
