The builder should actually be allowed to override the complete
CFLAGS and LDFLAGS settings, but for historic reasons, this is
currently not possible and you're right: OPT was meant to be overridden
by the user and BASECFLAGS is reserved for configure use.

Since just adding the CFLAGS to the linker invokation breaks on
various platforms (the linker doesn't expect compiler flags or
complains due to duplicate flags), this simple route will not work.

I suppose the best way to do this is by adding an extra check
to configure.in that tests whether the new GCC 4.5 option is supported
and also check whether CFLAGS can be passed to the
linker. If this test succeed, the configure script could then
add CFLAGS to the linker invokations or perhaps merge CFLAGS into
LDFLAGS.
