I apologize for the very late reply.
I'm not sure what you mean with "standard envvars" here. Is it "CFLAGS"
and "LDFLAGS"? If that's what you mean, I disagree.
CFLAGS handling is correct this way - CFLAGS should represent the final
list of options passed to the compiler. Typically the Makefile
assembles this list from internal project settings and user input.
Currently, setting OPTFLAGS is the preferred way to customize
multipath-tools build.
If changes are needed, I'd prefer Bart's suggestion.
