arc: stand: Switch to libsa/getopt, NFCI

Explicitly strip debug info on calling objdump for ecoff boot binaries.

As noted by martin@ on tech-toolchain@, release binaries are built
with MKDEBUG=yes so standalone binaries should explicitly remove
debug info generated by -g option.
https://mail-index.netbsd.org/tech-toolchain/2020/06/02/msg003809.html

Should be pulled up to netbsd-9.
(ARC BIOS gets confused by debug info sections in ecoff binaries
and boot binary in 9.0 doesn't work)

Drop bootprog_maker (formerly enabled by -M) and bootprog_date (formerly
disabled by -D) from the output of newvers_stand.sh. Change -D to the

wasn't present before. Platforms that didn't use -D don't depend on
MKREPRO now either.

Switch remaining platforms to modern CPP for assembler.
