>Description:
glxinfo crashes on MesaLib 20.0.2 on moduler X in NetBSD-current/i386.

I was running modular x with nvidia GT730 card in NetBSD-current,
After updated MesaLib from 19.2.7 to 20.0.2, was running glxinfo in xterm,
was saw out to below messages at terminal.

>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.

 This problem due not occur under all configurations. For example it
 does not happen with modesetting on i915 or radeon. It can be triggered
 on those by setting environment variables:

 GALLIUM_DRIVER=llvmpipe LIBGL_ALWAYS_SOFTWARE=true

 This is also true for x86_64. What happens then is that glGetString()
 doesn't get resolved to any implementation and glxinfo crashes.

 There is only one call to u_current_set_table and we do return the same
 table pointer at the time when glGetString() gets called so I don't
 think the problem is in the patch. There may be code on in some of the
 backends that make false assumptions about the startup value of TLS
 variables. Need to compare with pkgsrc on Linux.
