Why aren't you adding it to PG_CPPFLAGS? That should work, and I think
that's what several contrib modules are using.
My understanding of CUSTOM_COPT is that it's for use in Makefile.custom,
not for contrib modules etc?

It probably wouldn't hurt to add COPT that to the respective rules in
Makefile.global.in in some way. Shouldn't be too hard to do, if you want
to write a patch. Probably just apply it to BITCODE_CFLAGS as well.
