Subject: rules: add per-library EXTRA_HC_OPTS

Sometimes it's handy to change a compiler flag
for a library in stage{0,1,2}.

Usage example:

    libraries/binary_EXTRA_HC_OPTS += -O1
    libraries/containers_EXTRA_HC_OPTS += -O1
    libraries/bytestring_EXTRA_HC_OPTS += -O1

Here override default -O2 defined in .cabal files
for these libraries to speed build up.
