3.0: linker error with --disable-optimizations and --enable-esi

Hi,

I noticed that squid-3 does not seem to like --enable-esi in conjunction
with --disable-optimizations. A build where both options are defined
fails as follows; builds where either option is defined work.

(This is 3.0.STABLE12 on FreeBSD 7, first observed on amd64 by the
FreeBSD ports committer, reproducible on a physically different machine
on i386 by me. Compiler is FreeBSD's gcc-4.2.1 system compiler. Other
versions of FreeBSD were not tested. libxml2 is located in
/usr/local/lib/.)

Build environment:

$ make -DWITH_SQUID_DEBUG -DWITH_SQUID_ESI -VCONFIGURE_ENV -VCONFIGURE_ARGS
