Subject: (all.build): New rule for making gcc with a cross-compiler.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=057f494bb864e11120511dc8ba4e2b8f3916650a;p=gcc.git

(all.build): New rule for making gcc with a cross-compiler.

(install.build): New target.
(line 271): Add `####build overrides'.
(gen*.o): Depend on hconfig.h, not config.h.
($(HOST_PREFIX_1)rtl.o, $(HOST_PREFIX_1)print-rtl.o,
 $(HOST_PREFIX_1)rtlanal.o, $(HOST_PREFIX_1)obstack.o,
 $(HOST_PREFIX_1)malloc.o): Add final `h' to the regexp to replace.

(gcc.xtar): Fix typo in last change.
(mostlyclean): Don't use $(MAKEFLAGS) for objc subdir stuff.
