Fixed the fix for not using -fomit-frame-pointer with -pg. The previous

Browse Source 
fix stopped it being used in all cases, because substitution on unset
variables does not work.

When profiling, put -malign-functions=4 in CFLAGS instead of in PROF.
This fixes the histogram counts for profiling support functions.  It
gives bogus but harmless extra alignment for genassym etc.
