[PATCH util-modular 1/4] build.sh: drop passing environment variables to configure

[Peter Hutterer]

configure says they are "Some influential environment variables" and we don't
touch them anywhere within build.sh. So if they're already set, they'll be set
for configure anyway.

The only exception is CFLAGS which is modified with -g. Just export that one
where we change it and move on.
