Compile pr37870.c with -mlong-double-80

On x86, the "long double" type is platforma specific, which may be the
same as double or __float128.  Since pr37870.c requires 80-bit floating
point type, it should be compiled with -mlong-double-80.

	* gcc.target/i386/pr37870.c (dg-options): Add -mlong-double-80.
