Migrating a Gentoo install to libxcrypt

This is a set of instructions for migrating a Gentoo glibc system's libcrypt provider from glibc[crypt] to libxcrypt[system].

See wiki notes for background, etc.

Alpine Linux
Arch Linux
Debian, Ubuntu (on for most arches)
Fedora does it via spec files globally, not via toolchain
Gentoo (on for almost every arch by default, obviously in Gentoo you can toggle it easily if you want)
openSUSE has an interesting gcc-pie package instead which provides a spec file
Void Linux

These instructions cover:

building a cross toolchain
populating the new ROOT
making it chrootable using qemu-user to easily run "native" builds or tests (this is like a stage3 at the end)

You do not need to follow through to the end if you don't need a stage3-like root.

	## Description:
	## Commits all changes with a given template
	## Can exclude by maintainer.
	## Useful for e.g. big batch changes like a sed across tree

	## Usage:
	## - bash ~/scripts/commit-changed-pkgs

	# -fdiagnostics-color=always: just for colour
	# -frecord-gcc-switches: must be in ALL FLAGS (harmless but not needed in LDFLAGS) to be effective, or Portage skips it
	COMMON_FLAGS="-O2 -pipe -march=native -fdiagnostics-color=always -frecord-gcc-switches"
	CFLAGS="${COMMON_FLAGS}"
	CXXFLAGS="${COMMON_FLAGS}"
	FCFLAGS="${COMMON_FLAGS}"
	FFLAGS="${COMMON_FLAGS}"
	# You can use ${COMMON_FLAGS} here, but please remember to include as-needed manually then.
	LDFLAGS="${LDFLAGS} -Wl,--defsym=__gentoo_check_ldflags__=0"

	Hi all,

	TL;DR: We really need help! There aren't many developers in Gentoo
	interested in working on Itanium. Come hang around in #gentoo-ia64
	on libera.chat (IRC) if you're interested in helping.

	As discussed in the recent Gentoo Council meeting [0], concerns were raised
	about the status of Itanium (IA64) and I agreed to write to gentoo-dev to
	assess the level of interest & put out a call for volunteers.
