tinyalsa: Fix overwrite of asound.h

As stated by Maarten ter Huurne on the mailing list, the install of the
asound.h headers overwrite the one from the toolchains or kernel
headers.
Since tinyals's header is only a subset of the 'real' asound.h, there is
no need to overwrite it.

libxml2: explicitly state zlib dir

Pass the zlib directory prefix to --with-zlib otherwise it expands into
absolute (distribution) directories leading to bad test results in
configure. Fixes:
