[Mesa-dev] [PATCH] Android: gallium_dri: pass dri.sym to linker

[Rob Herring]

Pass the dri.sym version script to the linker. This ensures only
explicitly exported symbols are exported and shrinks the library by up
to 60KB.

We need to pass "--undefined-version" because the Android build system
sets --no-undefined-version by default and we get an error on
__driDriverExtensions without the option.
