[VDPAU] [PATCH 1/4] trace: use intermediate static library in the build

[Emil Velikov]

Compile the source into a static library, to prevent C++ linkage. The
latter of which unnesseserally pulls libm, libgcc_s and libstdc++ as
dependencies.

This also reduces the size of the stripped library by ~8% (51 > 47KiB).
