That really wasn't what you wanted to do.  There's a package in the "L"
Slackware installation series that contains the compile-time half of
glibc.  You only had the run-time half installed.

Again, you really don't want to do that.  If any of the configuration
options are different, you might end up with programs that won't run on
the libc that you have installed in /lib.

Set CFLAGS and LDFLAGS appropriately prior to calling configure:

CFLAGS='...' LDFLAGS='...' ./configure

It goes in LDFLAGS or CFLAGS, I don't remember which.

rm -rf /usr/glibc-2.2.5
cd /tmp
$DIST=ftp://ftp.slackware.com/pub/slackware/slackware-8.1
wget $DIST/slackware/l/glibc-2.2.5-i386-2.tgz
pkgtool

Select "Current", and then install the glibc package from the
distribution.
