[PATCH] Remove support for PowerPC e500 / SPE ISA extension.

- Subject: [PATCH] Remove support for PowerPC e500 / SPE ISA extension.
GCC 9 dropped support for the e500 variation of PowerPC, so I suggest
we should follow suit.
This patch was developed by grepping for “e500”, “__SPE__”, and
“__NO_FPRS__”, and may not eliminate every vestige of e500 support.
Also, I left most uses of __NO_FPRS__ alone, as it was not clear to me
whether they might be relevant to normal embedded PowerPC with
soft-float.
Tested by attempting to configure with
CC=powerpc-x-linux-gnu-gcc --host=powerpc-x-linux-gnuspe
(this errors out, as intended) and by cross-building with
CC=powerpc-x-linux-gnu-gcc --host=powerpc-x-linux-gnu
(this still works).

GCC 9 dropped support for the e500 variation of PowerPC. Follow suit.
* 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 e500 code.
Issue an #error if used with an e500 compiler.
