+ Readded -pipe option for gcc (except djgpp) and icc/linux family
compilers in a more sophisticated way. Now -pipe option is only
used when hbmk2 controls the output filename, and in such case
the output filename will always be deleted by hbmk2 if the
C compiler returned error. This way -pipe can never leave
faulty or dummy object files on disk, confusing incremental builds
or just leaving trash behind. BTW, it'd be interesting to
know why such seemingly buggy behavior hasn't been fixed in gcc
in the last 6-7 years... (making -pipe option useless for Harbour
build process f.e.)
