ldconfig miscompile on i386

[Jeff Bailey <jbailey@nisa.net>]

I figured out why the Debian package was miscompiling ldconfig and a
compile from the same sources was not:

We were setting both CFLAGS and BUILD_CFLAGS in a configparms file.

CFLAGS = -pipe -O2 -fstrict-aliasing
BUILD_CFLAGS = -O2

Is apparently not the right things to have in there anymore if you
want a working ldconfig on i386.

I will probably continue to persue this at some point to figure out if
it's a miscompile or not, but I have a catgets testsuite failure to
figure out first.

Tks,
Jeff Bailey
