Use build_cflags when setting ASMFLAGS 

While the current implementation works on Fedora, on c9s/rhel
the CFLAGS haven't been set at this point yet, so we are missing
the -fcfprotection flag in ASMFLAGS. Using build_cflags avoids
this ordering problem.

Additionally, add -Wl,-z,cet-report=error to the libLLVM.so linker
flags, so we can detect such issues earlier in the future.
