autoconf

• Depends on m4 and itself
• Depends on help2man; touch missing .1.t files (-j1 does not work)
• autoreconf depends on autopoint from gettext-tiny
• Build system automatically sets M4=/usr/bin/m4 and EMACS=no
• lto works without patches on glaucus
• binutils does not provide /usr/share/info/standards.info
• Test suite requries GNU m4, and perl to run autom4te on tests/wrapper.in
• Tests 227 and 351 are broken on Adelie and Arch
• Tests are disabled on Alpine
