Remove support for PowerPC SPE extension (powerpc*-*-*gnuspe*).
GCC 9 dropped support for the SPE extensions to PowerPC, which means
powerpc*-*-*gnuspe* configurations are no longer buildable with that
compiler. This ISA extension was peculiar to the “e500” line of
embedded PowerPC chips, which, as far as I can tell, are no longer
being manufactured, so I think we should follow suit.
This patch was developed by grepping for “e500”, “__SPE__”, and
“__NO_FPRS__”, and may not eliminate every vestige of SPE support.
Most uses of __NO_FPRS__ are left alone, as they are relevant to
normal embedded PowerPC with soft-float.
* sysdeps/powerpc/preconfigure: Error out on powerpc-*-*gnuspe*
host type.
* scripts/build-many-glibcs.py: Remove powerpc-*-linux-gnuspe
and powerpc-*-linux-gnuspe-e500v1 from list of build configurations.
* sysdeps/powerpc/powerpc32/e500: Recursively delete.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/e500: Recursively delete.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/context-e500.h:
Delete.
* sysdeps/powerpc/fpu_control.h: Remove SPE variant.
Issue an #error if used with a compiler in SPE-float mode.
