[igt-dev] [PATCH i-g-t 3/4] assembler/gen4asm.h: Make struct src_operand extern

[Lyude]

From: Lyude Paul <lyude at redhat.com>

Another spot where we fail compilation with -fcommon, due to src_operand
getting included in multiple translation units without being marked as
extern:

/usr/bin/ld:
assembler/1ca89e8@@intel-gen4asm at exe/meson-generated_gram.c.o:assembler/gen4asm.h:119:
multiple definition of `src_operand';
assembler/1ca89e8@@intel-gen4asm at exe/meson-generated_lex.c.o:assembler/gen4asm.h:119:
first defined here
/usr/bin/ld:
assembler/1ca89e8@@intel-gen4asm at exe/main.c.o:assembler/gen4asm.h:119:
multiple definition of `src_operand';
assembler/1ca89e8@@intel-gen4asm at exe/meson-generated_lex.c.o:assembler/gen4asm.h:119:
first defined here

So, fix this by marking struct src_operand as extern.
