glibc is designed to be built in a separate build directory.

The $srcdir/Makefile.in is processed by the autotools to be come
$builddir/Makefile.

The $srcdir/Makefile.in is designed to run commands from $srcdir/Makefile.

Where $srcdir is the source directory and $builddir is the build directory.

Does that help?

Cheers,
Carlos.
