Message:

Replace --no-{rtti,exceptions} by -fno-{rtti,exceptions}

This improves compatibility with clang. Moreover, to the best
of my knowledge, the --no-* variants are undocumented to start with.
At least the GCC manuals for all versions from 2.95.3 till 4.7.2
only list the -fno-* variants, as far as I could tell.
