If one of the perlasm xlate drivers crashes, OpenSSL's build will
currently swallow the error and silently truncate the output to however
far the driver got. This will hopefully fail to build, but better to
check such things.

Handle this by checking for errors when closing STDOUT (which is a pipe
to the xlate driver).

This is the OpenSSL 1.1.1 version of
https://github.com/openssl/openssl/pull/10883 and
https://github.com/openssl/openssl/pull/10930.

The assembler already knows the actual path to the generated file and,
in other perlasm architectures, is left to manage debug symbols itself.
Notably, in OpenSSL 1.1.x's new build system, which allows a separate
build directory, converting .pl to .s as the scripts currently do result
in the wrong paths.

This also avoids inconsistencies from some of the files using $0 and
some passing in the filename.

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.

This gets rid of the BEGINRAW..ENDRAW sections in crypto/md5/build.info.

This also moves the assembler generating perl scripts to take the
output file name as last command line argument, where necessary.

Make all scripts produce .S, make interpretation of $(CFLAGS)
pre-processor's responsibility, start accepting $(PERLASM_SCHEME).
[$(PERLASM_SCHEME) is redundant in this case, because there are
no deviataions between Solaris and Linux assemblers. This is
purely to unify .pl->.S handling across all targets.]
