a more universal BOOT_CFLAGS/BOOT_LDFLAGS

[Paul Jarc]

While building gcc, I want to pass a certain set of flags to every
compilation that uses a gcc we've just built.  (More accurately, I
want to pass these flags to absolutely every compilation whatsoever,
but for the cases where the installed gcc is used, I'm using a wrapper
script that's ahead of the real gcc in $PATH.)  I've tried
BOOT_CFLAGS/BOO_LDFLAGS and TCFLAGS, but it seems that neither of
these is used while compiling crtbegin.o.  Is there any set of
Makefile variables that will collectively cover absolutely all cases
where a newly-built gcc is used?
