+kmsdrm: Fix busy-loop within libc's dlopen()
+For some obscure reason, the order in which the libdrm/libgbm libraries
+are loaded matters.
+
+Without this fix, the first call to check_modesetting() will work and
+load then unload all symbols properly, but the second call to this
+function will lock up as soon as dlopen() is called on libdrm.
+
+Swapping the order in which the libdrm and libgbm libraries are loaded
+is enough to fix (or work around?) this issue.
+
+Fixes #4891:
