Convert entry_x86_tsd.h to PIC
The x86 assembly language stub in src/mapi/entry_x86_tsd.h does not generate
PIC (position-independent code). This causes text relocations, which are by
default treated as an error by LLVM's lld linker (now used by FreeBSD and
OpenBSD) when building a shared library.
/usr/bin/ld: error: can't create dynamic relocation R_386_32 against symbol:
_glapi_Dispatch in readonly segment; recompile object files with -fPIC
<span class="quote">>>> defined in .libs/shared_glapi_libglapi_la-u_current.o
>>> referenced by entry.c
>>> .libs/shared_glapi_libglapi_la-entry.o:(.text+0x1)</span >
The accompanying minimal diff remedies this by generating PIC code. This is
mostly copied from the neighboring entry_x86_tls.h.</pre>
