(cross/mingw-binutils) fix build, taking care ld/genscripts.sh bash issue

 - The problem is:
	--- all-ld ---
	.././ld/genscripts.sh: 411: Syntax error: Bad substitution
	*** [ei386pe.c] Error code 2

 - patch-ld_genscripts.sh seems addressing this issue, but does not seem
  working correctly

 - So, there may be better solution, but sorry for adhoc fix (as usual)
