Prior to commit 2c03ec15307b567fd2250fe2a7981a89d19b87a9 (from 2002),
--enable-alsatest would cause an AC_TRY_RUN test to be executed, which
doesn't work in a cross-compiled environment.

There is by the way a remainder from that in utils/alsa.m4:

  AS_HELP_STRING([--disable-alsatest], [Do not try to compile and run a test Alsa program]),

See how it says "Do not try to compile and *run* a test Alsa program" ?

I think --disable-alsatest could be removed now. In addition, upstream
seems to have improved yesterday the detection of the topology library
in alsa-lib commit ad8527d81b09c4d0edd054b5b1468ce1c50b23cb. Could you
try this instead ?

Thanks,

Thomas
