Yes, it's been common in gentoo land in recent years for ebuilds to
ignore the user supplied CFLAGS entirely or strip out certain flags to
stop people from shooting themselves in the foot.

Unlike for C, for Haskell compilers there are fewer interesting
optimisation or platform specific flags (think -O?, -march=???,
-fbe-really-sloppy-with-floating-point etc etc). This is a good thing
since there is less desire to fiddle.

I agree, for our various Haskell ebuilds we do not provide any easy way
for users to override HCFLAGS.
