stress-ng: Do not enforce gold linker

This can then be controlled by yocto environment through LDFLAGS if
needed since we support multiple linkers and distro policy may want a
different linker, moreover gold fails on ppc32 to link since its missing

Fixes errors like below on ppc/gold + clang

/usr/lib/clang/15.0.6/lib/linux/libclang_rt.builtins-powerpc.a(mulsc3.c.o): unsupported -mbss-plt code

+Subject: [PATCH] Pass LD_GOLD=1 via makefile to enable gold linker
+
+Current logic prefers gold if a toolchain has gold linker installed and
+does not offer any option to chose default linker which might not be
+gold linker. Its better to pass this control to user instead of auto
+detecting and deciding.
