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.

Upstream-Status: Inappropriate [configuration]
