alsa-lib: check if wordexp is supported in libc
eglibc could be configured to build without the wordexp feature. To ensure that the wordexp feature could be used, the configure script must check if wordexp() is supported in libc in addition to checking if wordexp.h exists. Signed-off-by: Hong H.

+Subject: [PATCH] Check if wordexp function is supported
+
+eglibc could be configured to build without wordexp, so it is not enough
+to check if wordexp.h exists (the header file could be installed, but it's
+possible that the wordexp() function is not supported). An additional
+check if wordexp() is supported by the system C library is needed.
