Changed in V3:
Rebase it against master as we have already
merged the first version.
Change in V2:
As the upstream of gcc suggested:
- The previous fix is too hack;
- Use '$(ALL_HOST_OBJS) : | $(generated_files)' rule to
handle the dependency.
Test Steps:
1. For reproducing the issue every time, manually modify
gcc/Makefile.in to delay the generation of config.h:
...
diff --git a/gcc/Makefile.in b/gcc/Makefile.in
index c4daf69..c502898 100644
--- gcc-4.9.0/gcc/Makefile.in
