This patch, relative to a tree with my patch

reduces the number of explicit compilation rules in gcc/ and
subdirectory makefiles by using CFLAGS-$@ settings when a target needs
extra compiler options.
Not fixed are rules for building driver files (involving SHLIB_LINK)
or those where the simple relation between .c and .o file names does
not apply (many of which could be fixed by moving the .o files in the
object tree to locations directly corresponding to the source files).
One linking rule that used $(COMPILER) instead of $(LINKER) for no
apparent reason was changed to use $(LINKER) instead of masquerading
as a compilation rule.
This is inspired by some of the cleanups in Tom's automatic dependency
generation patch that had to be reverted in 2008, the idea being that
such cleanups are of value on their own even without automatic
dependency generation and would also facilitate any future attempt at
automatic dependency generation.
Bootstrapped with no regressions on x86_64-unknown-linux-gnu. OK to
commit (the first patch this is relative to and this one)?
Ok, nice cleanup.
