flag-o-matic.eclass: Strip LDFLAGS unsupported by the C compiler, #621274
Include LDFLAGS in the variables stripped by strip-unsupported-flags.
The code reuses the current functions for testing CC, and so only remove
LDFLAGS that are rejected by the C compiler and not the linker. This
solves the case of bug #621274 where LDFLAGS contained GCC-specific
-flto flag.
