And it looks more and more like ALSA bug to me.
The two relevant points are:
1) ALSA means Advanced _Linux_ Sound Architecture, the "Linux" word means
Linux only;
2) 'libtool' is intended to abstract out complexities/nuances of library
creation on different OSes, it works on a whole lot of UNIXish systems, even
for cross-compiling and linking Windows applications, i.e. 'libtool' is
a cross-platform tool by design/construction.
So, for ALSA, i.e. for Linux only, one doesn't need 'libtool' in the first
place, and if using 'libtool' causes problems, the root cause of the problems
is the decision of ALSA team to use 'libtool'.
Regards,
Sergei.
