[Ada] Set target_cpu to x32 for x86_64-linux-gnux32

Since the x86_64-linux-gnux32 compiler is actually an x32 compiler, set
target_cpu to x32 for x86_64-linux-gnux32.

	PR ada/103538
	* gcc-interface/Makefile.in (target_cpu): Set to x32 for
	x86_64-linux-gnux32.

(cherry picked from commit 2cef99175af1ad95283d4b35bced73c3a510f6d6)
