Maybe we should make those repairs rather that introduce one more option?

Debian unstable: glib 2.2.3, Autoconf 2.58.  I'm using Automake 1.8
installed in /usr/local.

It's better to set variable on the command line:
./configure LDFLAGS="-Wl,-static"

Works for me, even if I use the environment:

checking for pkg-config... /usr/bin/pkg-config
checking for glib-2.0... yes
checking GLIB_CFLAGS... -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include
checking GLIB_LIBS... -lglib-2.0

Since the error is on your side, you should post details, not me.  Check
config.log for relevant error messages.

I think you have libglib.a but not libglib-2.0.a.  The problem is either
in the gentoo package or in pkg-config or in glib.m4.  It depends on who
misunderstood whose intentions.  You may want to research this question or
at least file a bug with gentoo.  Even if problem is elsewhere, another
distibution (Debian) made the static library compatible with pkg-config
and glib.m4, and so should gentoo.

Actually, the error messages would be more interesting than the command
line.  I have no idea if those messages are related to static linking.

I could not reproduce this problem.

That would be equivalent to what you did initially:
./configure LDFLAGS="-Wl,-static"

Adding an option doesn't automatically solve any problems with the
functionality it stands for.
