The multi-build.in file in libgloss duplicates common multilib logic
in the root source tree. Document it a bit, and rename the rule so
it doesn't clash with the common multi-do rule. This will let us use
them in the same makefile so we can merge aarch64/ & arm/ up (as the
only targets that use this local multi-build.in atm).
Depending on the processing order of rules when installing in parallel,
these install rules might be processed before some other rule happens
to create the respective dirs. Make sure each one creates the needed
dirs before installing into them.
This uses the new recursive build target in multi-build.in
The new spec files are:
For AArch32/ARM (m for mixed mode):
- rdimon-v2m.specs
- aprofile-validation-v2m.specs
- aprofile-ve-v2m.specs
These spec files will be using the new libraries generated
by multi-build.in.

libgloss:
* arm/Makefile.in: Add newlib/libc/machine/arm to the include path if
newlib is present.
* arm/arm.h: Include acle-compat.h.
(THUMB_V7_V6M): Rename to ...
(PREFER_THUMB): This. Use ACLE macros __ARM_ARCH_ISA_ARM instead of
__ARM_ARCH_6M__ to decide whether to define it.
(THUMB1_ONLY): Define for Thumb-1 only targets.
(THUMB_V7M_V6M): Rename to ...
(THUMB_VXM): This. Defined based on __ARM_ARCH_ISA_ARM, excluding
ARMv7.
* arm/crt0.S: Use THUMB1_ONLY rather than __ARM_ARCH_6M__,
!__ARM_ARCH_ISA_ARM rather than THUMB_V7M_V6M for fp enabling, and
PREFER_THUMB rather than THUMB_V7_V6M. Rename other occurences of
THUMB_V7M_V6M to THUMB_VXM.
* arm/linux-crt0.c: Likewise.
* arm/redboot-crt0.S: Likewise.
* arm/swi.h: Likewise.
* arm/trap.S: Likewise.
newlib:
* libc/machine/arm/memcpy-stub.c: Use ACLE macros __ARM_ARCH_ISA_THUMB
and __ARM_ARCH_ISA_ARM to check for Thumb-2 only targets rather than
__ARM_ARCH and __ARM_ARCH_PROFILE.
* libc/machine/arm/memcpy.S: Likewise.
* libc/machine/arm/setjmp.S: Likewise for Thumb-1 only target and
include acle-compat.h.
* libc/machine/arm/strcmp.S: Likewise for Thumb-1 and Thumb-2 only
target and include acle-compat.h.
* libc/sys/arm/arm.h: Include acle-compat.h.
(THUMB_V7_V6M): Rename to ...
(PREFER_THUMB): This. Use ACLE macro __ARM_ARCH_ISA_ARM instead of
__ARM_ARCH_6M__ to decide whether to define it.
(THUMB1_ONLY): Define for Thumb-1 only targets.
(THUMB_V7M_V6M): Rename to ...
(THUMB_VXM): This. Defined based on __ARM_ARCH_ISA_ARM, excluding
ARMv7.
* libc/sys/arm/crt0.S: Use PREFER_THUMB rather than THUMB_V7_V6M and
rename THUMB_V7M_V6M into THUMB_VXM.
* libc/sys/arm/swi.h: Likewise.
* arm/Makefile.in: Add Linux syscall interface.
* arm/linux-crt0.S: New file.
* arm/linux-syscall.h: New file.
* arm/linux-syscalls0.S: New file.
* arm/linux-syscalls1.c: New file.
* arm/configure.in: Check the value of newlib-may-supply-syscalls
enablement variable to determine if crt0 should or should not be
built.
* arm/configure: Regenerated.
* arm/Makefile.in: Changed to look at @BUILD_CRT0_TRUE@ and
@BUILD_CRT0_FALSE@ variables set in configure to determine
if crt0.o should be built and installed.
* arm/crt0.S: Copied from newlib and it now also sets up stacks for
FIQ and IRQ mode, plus calls hardware_init_hook() and
software_init_hook() if present.
* arm/libcfunc.c, arm/swi.h, arm/syscalls.c: Copied
from newlib.
* arm/Makefile.in: Build crt0.o, rdpmon-crt0.o, rdimon-crt0.o,
librdpmon.a, librdimon.a - support file for "bare" setup, as well
as "RDP" and "RDI" monitors.
* arm/coff-rdpmon.specs, arm/elf-rdpmon.specs,
arm/coff-rdimon.specs, arm/elf-rdimon.specs: gcc specs files to go
with above mentioned support libs and startfiles.
