tcg/i386: Use GDB JIT debugging interface only for hosts with ELF
Not all i386 / x86_64 hosts use ELF. Ask the compiler whether ELF is used. On w64, gdb crashes when ELF_HOST_MACHINE is defined. Cc: Blue Swirl <blauwirbel@gmail.com> Acked-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Stefan Weil <sw@weilnetz.de>
