rs6000: Allow -mlong-double-64 after -mabi={ibm,ieee}longdouble [PR104208,
PR87496]
The glibc build is showing a build error due to extra "error" checking from
my
PR87496 fix. That checking was overeager, disallowing setting the long
double
size to 64-bits if the 128-bit long double ABI had already been specified.
Now we only emit an error if we specify a 128-bit long double ABI if our
long double size is not 128 bits. This also fixes an erroneous error when
-mabi=ieeelongdouble is used and ISA 2.06 is not enabled, but the long
double
size has been changed to 64 bits.
