- 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:
