[Bug bootstrap/25207] New: bootstrap fails on libjava if alsa headers present but no -lasound.

[hp at gcc dot gnu dot org]

This is on FC4 with alsa-lib{.i386,x86-64} installed but only
alsa-lib-devel.x86_64 (no alsa-lib-devel.i386). Hence the header
files are there, but not the libraries when building the -m32 multilib.

It looks as if configury looks for and finds header files but it's overlooked
to also look for "asound" libraries:
...
checking for unistd.h... (cached) yes
checking alsa/asoundlib.h usability... yes
checking alsa/asoundlib.h presence... yes
checking for alsa/asoundlib.h... yes
checking dssi.h usability... no
...

I'll work around this by installing alsa-lib-devel.i386
