Hi Nick,

I found that GCC already has a superset of this patch.
Commit 84401ce5fb4e ("[PATCH 1/5] Makefile.in: Ensure build CPP/CPPFLAGS
is used for build targets") is the one.

I will commit my patchset as is (because this is sufficient to resolve
Binutils side issue) but also will seek an opportunity to sync with this
when I revisit configure scripts again (currently, I'm working on RISC-V
(various parts) and disassembler improvements on Arm and AArch64).

Thanks,
Tsukasa
