$ export PATH=~/.bin:$PATH
$ for cc in CC cc c++ gcc g++ cpp; do ln -s /usr/bin/false ~/.bin/${cc}; done
ghc-boot build wants CC being set in environment, not in a makefile
(e.g. make.conf). And when set its runtime still uses `gcc' compiler
ignoring CC unlike, say, ghc/ghc.wrapper.
||| replace only `gcc' with symlink to `false'

# use default `CC = cc' from sys.mk
# or define `CC = clang' in make.conf

The first part seems trivial. As for `-pgmc ${CC}' not sure yet.
