Seems odd as mGbmDevice isn't null until dereferenced later in
DMABufSurface.cpp
https://hg.mozilla.org/releases/mozilla-release/file/0c479fee3a5092bea2bfdb32cfdcc66039544c3e/widget/gtk/DMABufLibWrapper.cpp#l253

https://hg.mozilla.org/releases/mozilla-release/file/0c479fee3a5092bea2bfdb32cfdcc66039544c3e/widget/gtk/DMABufLibWrapper.cpp#l125

https://hg.mozilla.org/releases/mozilla-release/file/0c479fee3a5092bea2bfdb32cfdcc66039544c3e/widget/gtk/DMABufSurface.cpp#l383

I had a similar problem before due to LDFLAGS+=-Wl,--as-needed in Mk/bsd.gecko,
but removing it did not help here. I have no idea about C++ but I'll leave a
note if I figure the cause of DMABufSurface.cpp getting a nullptr.
