[PATCH, rs6000, committed] Fix AIX bootstrap (don't call asprintf)

[Bill Schmidt]

Hi,

My recent commit broke bootstrap for AIX because I was calling asprintf 
without pulling it in from libiberty.h.  Unfortunately, there is a name 
collision between libiberty.h and string.h that I don't immediately know 
how to resolve, so rather than fight it I've just reverted to using 
malloc and sprintf.

Bootstrapped on powerpc64le-linux-gnu, committed as obvious. Sorry for 
the trouble!

Bill

	* config/rs6000/rs6000-gen-builtins.c (parse_bif_entry): Don't call
	asprintf, which is not available on AIX.
