[PATCH]: Remove sparc-linux long double size override.

[David Miller <davem@davemloft.net>]

We realized many years ago that using 64-bit long doubles
for 32-bit sparc was a mistake and migrated all of userland
over to using proper 128-bit long doubles.

There isn't a way to really detect this at run time, but I
think it's better to move forward and delete this override
and get current systems right rather than support ancient
ones.

This fixes another swath of testsuite failures.

Ok to apply?

	* sparc-linux-tdep.c (sparc32_linux_init_abi): Remove
	long double size override, Linux does use 128-bit now.
