An earlier patch fixed the problem for classic drivers, however Gallium
was still left broken. This patch applies the same workaround to
Gallium, when compiled for Android. Following is a quote from the
original patch:
0cbc90c57cfc mesa: dri: Add shared glapi to LIBADD on Android
/system/vendor/lib/dri/*_dri.so actually depend on libglapi: without
this, loading the so file fails with:
cannot locate symbol "__emutls_v._glapi_tls_Context"
On non-Android (non-bionic) platform, EGL uses the following
workflow, which works fine:
dlopen("libglapi.so", RTLD_LAZY | RTLD_GLOBAL);
dlopen("dri/<driver>_dri.so", RTLD_NOW | RTLD_GLOBAL);
However, bionic does not respect the RTLD_GLOBAL flag, and the dri
library cannot find symbols in libglapi.so, so we need to link
to libglapi.so explicitly. Android.mk already does this.
