Add a number of binutils replacements from the elftoolchain project

[emaste]

Summary

• addr2line
• elfcopy / strip / mcs
• nm
• size
• strings

[emaste]

Right now this will install strip as bsdstrip, along with elfcopy and mcs. We can probably do without the latter.

My goal would be to bring in later on size, strings, and nm, and add a knob to use them instead of the GNU counterparts.

Will change to "r3076"

Should be LIBADD= elf elftc

Should be LIBADD+= archive

Ah, this is the contrib Makefile that's not used. I could strip it out of contrib perhaps to avoid confusion, but I think my preference is to leave vendor imports as-is.

Have a look at the lib/libelftc/Makefile.

I forgot to cancel my inline comments, but yes I saw after commenting inline :)

• Update libelftc to SVN r3076
• Update elfcopy to upstream SVN r3076
• Track libarchive API change
• Fix elftoolchain tools build on FreeBSD
• Remove non-FreeBSD bits for now
• Build infrastructure for elftoolchain tools

usr.bin/elfcopy/Makefile

not sure it's worth installing mcs
also bsdstrip.1 should be strip.1, this is an error in my rebasing

[emaste]

usr.bin/addr2line/Makefile

17–18

Seems unnecessary

[bapt]

If libelftc always implies libelf then you could just:

DPADD_elftc= ${DPADD_elf}
LDADD_elftc= ${LDADD_elf}

in src.libnames.mk

So everything linking to elftc will link to elf automatically and they only needs
LIBADD= elftc

Don't know it is worth or not in your case :)

lib/libelftc/Makefile

29

LIBADD= elf
but do you really need that given you are building an internallib?

31

Should be NO_MAN=yes

[emaste]

It looks like PR191587 https://bugs.freebsd.org/191587 is fixed with this change.
