According to
http://www.gnu.org/software/libtool/manual/html_node/LT_005fINIT.html, LT_INIT
will test some environment variables, CFLAGS being one of them. By moving the
LT_INIT macro from line 27 below line 274, CFLAGS is now defined according to
32 or 64 bit build (done between lines 240 and 270). That is, by setting
"--enable-32-bit" when building mesa (line 248), CFLAGS="$CFLAGS -m32" (line
250), thus LT_INIT will consider using 32 bit mode when initialized.
