a5aa63a456 Fix some assembler generating scripts for better unification
Some of these scripts would recognise an output parameter if it looks
like a file path.  That works both in both the classic and new build
schemes.  Some fo these scripts would only recognise it if it's a
basename (i.e. no directory component).  Those need to be corrected,
as the output parameter in the new build scheme is more likely to
contain a directory component than not.

bdbd3aea59 Consistently use arm_arch.h constants in armcap assembly code.
Most of the assembly uses constants from arm_arch.h, but a few references to
ARMV7_NEON don't. Consistently use the macros everywhere.

8eed3289b2 bn/asm/armv4-mont.pl: boost NEON performance.
Close difference gap on Cortex-A9, which resulted in further improvement
even on other processors.

11208dcfb9 ARMv4 assembly pack: implement support for Thumb2.
As some of ARM processors, more specifically Cortex-Mx series, are
Thumb2-only, we need to support Thumb2-only builds even in assembly.

c1669e1c20 Remove inconsistency in ARM support.
This facilitates "universal" builds, ones that target multiple
architectures, e.g. ARMv5 through ARMv7. See commentary in
Configure for details.
