>How-To-Repeat:

>Fix:
1. delete patches/patch-src_mapi_entry__x86__tls.
2. make mps.
3. make replace
4. work for me :)

I think that a matter of mentioned by this patch was cleared because of which
STUB_ASM_CODE and x86_current_tls macros on src/mapi/entry_x86_tls.h 
were rewrited when Mesa 19.3 was appeared. maybe. please to check it.
