AC_COMPILE_CHECK_SIZEOF

[Jones Desougi]

AC_COMPILE_CHECK_SIZEOF (in config/accross.m4) takes an optional argument
and uses it for two incompatible purposes. One is additional sizes to try
and the other is additional code sent to AC_TRY_COMPILE.
This affects mainline and the 3.4 branch. The gcc_AC_COMPILE_CHECK_SIZEOF
that was in 3.3.x used two optional arguments for this.
The optional argument does not appear to be used anywhere at this time.

This patch takes the approach of the old macro and applies to both
mainline and 3.4 branch:

	* accross.m4 (AC_COMPILE_CHECK_SIZEOF): Split self conflicting
	optional argument into two.
