0822d41b6d aes/asm/bsaes-armv7.pl: relax stack alignment requirement.
Even though Apple refers to Procedure Call Standard for ARM Architecture
(AAPCS), they apparently adhere to custom version that doesn't follow
stack alignment constraints in the said standard. [Why or why? If it's
vendor lock-in thing, then it would be like worst spot ever.] And since
bsaes-armv7 relied on standard alignment, it became problematic to
execute the code on iOS.

609b0852e4 Remove trailing whitespace from some files.
The prevailing style seems to not have trailing whitespace, but a few
lines do. This is mostly in the perlasm files, but a few C files got
them after the reformat. This is the result of:

  find . -name '*.pl' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//'
  find . -name '*.c' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//'
  find . -name '*.h' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//'

Then bn_prime.h was excluded since this is a generated file.

Note mkerr.pl has some changes in a heredoc for some help output, but
other lines there lack trailing whitespace too.

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.

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.
