build problam with 1.6.4 beta1

[Sam Hartman]

I'm having trouble getting the debian package to configure on 1.6.4
beta1.  The debian build scripts run configure as follows:

cd build && ../src/configure CFLAGS="-g  -O2 -D_REENTRANT" \
                --prefix=/usr --localstatedir=/etc --mandir=/usr/share/man \
                --with-system-et --with-system-ss --enable-fakeka \
                --enable-shared --with-ldap --without-tcl \
                --build i486-linux-gnu


Things work fine until it gets to running configure in pkinit.  Then
it complains that the definition of CFLAGS in the cache differs from
the definition on the command line and that I need to run distclean.
It seems that the one of the CFLAGS values is being prepended with an
extra space.

I am still trying to track down why this is the case.
