Otherwise, if we're trying to build a 32-bit Mesa on a 64-bit host
we wind up with -DUSE_X86_64_ASM, which is incorrect.

According to [1], host is "the machine that you are building for" and
target is "the machine that GCC will produce code for". In the context
of building GCC, I think this means that the resulting GCC binaries
will run on $host and will produce code for $target. In the context of
Mesa, I can't come up with a way that host != target makes sense.
docs/autoconf.html suggests using --build=x86_64-pc-linux-gnu
--host=i686-pc-linux-gnu to build on x86_64 for i686. Is that what
you're doing?
Thanks for the pointer to the docs! I forgot this was mentioned there.
I basically had my --host and --build mixed up.
Also, I was using "i686-linux-gnu" instead of "i686-pc-linux-gnu" (is
there really a difference)?
Let me see how far I get now that you set me straight...
OK, so the next problem is Mesa is trying to link with 64-bit libdrm
instead of the 32-bit one.
The command is:
libtool: link: g++ -fPIC -DPIC -shared -nostdlib
/usr/lib/gcc/x86_64-linux-gnu/4.9/../../../../lib32/crti.o

/usr/lib/x86_64-linux-gnu/libdrm.so: error adding symbols: File in wrong

collect2: error: ld returned 1 exit status
Note near the middle:
/usr/lib/x86_64-linux-gnu/libdrm.so
shortly followed by:
/usr/lib/i386-linux-gnu/libdrm.so
That's after I added PKG_CONFIG_PATH=/usr/lib/i386-linux-gnu/pkgconfig
during configuring. Without that, it only tries to link with the 64-bit
libdrm.
Any ideas?
