Thanxs for suggestions. I was able to compile both 32 bit and 64 bit on the RedHat machine with the following commands:
cd alsa-lib
./configure --libdir=/usr/lib64, make, make install
cd ../alsa-driver
./configure --libdir=/usr/lib64 --with-cards=dummy --with-sequencer=yes, make, make install
cd ../alsa-lib
./configure CFLAGS="${CFLAGS} -m32" LDFLAGS="${LDFLAGS} -m32", make, make install
cd ../alsa-driver
./configure CFLAGS="${CFLAGS} -m32" LDFLAGS="${LDFLAGS} -m32" --with-cards=dummy --with-sequencer=yes, make, make install
cd ../alsa-utils
./configure CFLAGS="${CFLAGS} -m32" LDFLAGS="${LDFLAGS} -m32", make, make install
ln -sf /usr/lib64/libasound.so.2.0.0 /lib64/libasound.so.2
ln -sf /usr/lib/libasound.so.2.0.0 /lib/libasound.so.2
However, now there's another strange problem. If I try to run any of the 32 bit utils (such as aplay or alsamixer) or 32 bit Skype (the symptoms are the same), I get the following error in my /var/log/messages:
Feb 13 22:55:57 project kernel: ioctl32(aplay:4326): Unknown cmd fd(3) cmd(81785501){01} arg(ffffd310) on /dev/snd/controlC0
It seems like 32bit <--> 64bit conversion by ioclt32 is not supported.
Does anyone have any ideas what am I doing wrong? Cheers!
Regards,
Blaz

Some earlier version worked for me building my x86_64 multilib system.
As I'm using neither RedHat nor Skype I don't know if there's an easier way
for you.
