Xwayland block SIGUSR1 signal for handling this signal. However, if some
weston plugins creates additional threads before xwayland is loaded,
this signal get delivered these threads and causes weston quit.
Therefore, we should set up SIGUSR1 blocking early so that these threads
can inherit the setting when created.

AC_SEARCH_LIBS is the recommended macro for these checks, unfortunately,
we use AC_CHECK_LIB instead, and even AC_CHECK_FUNC, when only one
AC_SEARCH_LIBS would be enough.
This wrapper macro is used much like PKG_CHECK_MODULES, as it defines
(and AC_SUBST) the PREFIX_LIBS variable itself.
It also avoids adding unnecessary stuff to LIBS.
