When building alsa-lib with the following settings

    CFLAGS='-O3 -pipe'
    CXXFLAGS='-O3 -pipe'
    LDFLAGS=-Wl,-O1		\
	-Wl,--as-needed		\
	-fuse-ld=lld		\
	-rtlib=compiler-rt	\
	-unwindlib=libunwind

the build fails with errors similar to

    ld.lld: error: version script assignment of 'ALSA_0.9.5' to symbol
	'alsa_lisp' failed: symbol not defined

This patch corrects that issue and additional issues found while making
corrections so alsa-lib will successfully build using clang and ld.lld.

This patch set was also submitted as a github PR
(https://github.com/alsa-project/alsa-lib/pull/376).
