It also complies with the GNU Coding Standard.

I am for this change, I think that having CPPFLAGS and other flags
work consistently is a useful feature as long as it doesn't conflict
with the requirements of the package in question e.g. glibc.

I can see an argument for *more* control over where options are added
to the build commands, but I see no good argument *against* what is
effectively a good practice of supporting CPPFLAGS per the GNU coding
standard.

Cheers,
Carlos.
