In commit fa6c7d1659 ("libdrm: fix
libatomic_ops linking"), a patch was added to switch to
PKG_CHECK_MODULES() to detect libatomic_ops instead of
AC_CHECK_HEADER.
However, as explained in
https://autotools.io/pkgconfig/pkg_check_modules.html:
"In contrast with almost all of the original macros, though, the default
action-if-not-found will end the execution with an error for not having
found the dependency."
This makes the configure script bail out when libatomic_ops is not
available, which is not what we want in libdrm's configure
script. This commit adjusts the PKG_CHECK_MODULES() call to avoid
failing.
