Subject: [PATCH] Generate proper DL_OPENGL value for linux

Since we rely on the dynamic linker to find the library for us via
dlopen(), we need to have DL_OPENGL be .so.N, not the full library
filename, as ldconfig doesn't cache the full filename

Use of TARGET_SONAME_FILE requires the library to be marked as SHARED,
not MODULE

This closes pull request #370
