[PATCH v5] i386 and x86_fenv.h support

[joel@rtems.org]

From: Joel Sherrill <joel@rtems.org>

Hi

I have posted multiple versions of this patch. The i386 builds
and tests fine on RTEMS. I cannot get the configure/Makefile
magic right for x86_64. Help is appreciated.

I added x86_64 to configure.host for libm_machine_dir and
x86_64 to libm/machine/configure.in.

The error messages in the log indicate that NEWLIB_CONFIGURE isn't
being expanded but libm/machine/x86_64/configure.in diffs as
nearly identical to the i386 and arm versions.

././config.cache --srcdir=../../../../../../newlib-cygwin/newlib/libm/machine/x86_64
configure: loading cache ../../.././config.cache
../../../../../../newlib-cygwin/newlib/libm/machine/x86_64/configure: line 1679: syntax error near unexpected token `../../..'
../../../../../../newlib-cygwin/newlib/libm/machine/x86_64/configure: line 1679: `NEWLIB_CONFIGURE(../../..)'
configure: error: ../../../../../../newlib-cygwin/newlib/libm/machine/x86_64/configure failed for x86_64
configure: error: ../../../../../newlib-cygwin/newlib/libm/machine/configure failed for machine
configure: error: ../../../../newlib-cygwin/newlib/libm/configure failed for libm

I really would appreciate help in figuring out what's not
bootstrapping correctly.

Thanks.
