Gaius Mulley f2872e00f6 PR modula2/111956 Many powerpc platforms do _not_ have support for IEEE754 
This patch corrects commit
r14-4149-g81d5ca0b9b8431f1bd7a5ec8a2c94f04bb0cf032 which assummed
all powerpc platforms would have IEEE754 long double.  The patch
ensures that cc1gm2 obtains the default IEEE754 long double availability
from the configure generated tm_defines.  The user command
line switches -mabi=ibmlongdouble and -mabi=ieeelongdouble are implemented
to override the configuration defaults.

Bootstrapped on power8 and power9 machines.
