Historically, PKGDESTDIR was only set during pkg_install, and
XBPS_PKGDESTDIR was set to indicate that we're in subpkg's
pkg_install.
However, from 0b95cb8f5d, (Merge xbps-src code to make it usable in
a standalone mode., 2014-03-22), PKGDESTDIR is always set,
regardless of states.
Let's drop all usages of XBPS_PKGDESTDIR.
While we're at it, error out of vmove is used outside of subpkg.
this introduces a new build-style void-cross, which can be used
to write system crosstoolchain templates; this is to reduce the
amount of maintenance, resolve existing problems with the cross
toolchain templates and remove repeated code
this will rewrite total paths to be relative to CCACHE_BASEDIR before caching,
helps prevent cache misses due to changed wrksrc with build systems like cmake
that use total paths in their Makefiles
git-worktree(1), and Git shared repository can use a plain text file
named `.git` at the root of working tree, containing `gitdir: <path>` to
point to the real directory that has repository.
See: gitrepository-layout(5).
But, that directory is usually inaccessible inside chroot.
In order to support git-worktree(1) and Git shared repository, compute
SOURCE_DATE_EPOCH from outside of chroot, and the chroot will carry it
over to inside chroot.
I've only tested again xbps-uunshare(1).
git-ls-files(1) is plumbing command, its output will never change
regardless of configuration, version.
git-status(1) output will be changed depends on configuration.
At least, 986d4dbc7d (common/environment/setup/git.sh: ensure untracked
files are checked., 2017-11-24) was added to address a different output
on `status.showUntrackedFiles`.
By doing this, also reduce a pipe, and a fork-exec.
Technically, git-log(1) is also a porcelain, but I _think_ `%ct` is
stable enough to stay there. If the day has come, that `git-log(1)` can
be replaced with:
git cat-file commit HEAD |
sed -ne '/^committer/{s/.* \([0-9]*\) [-+][0-9][0-9][0-9][0-9]$/\1/p;q}'
This checks if gcc-go-tools have been specified in host deps
and if so, use gccgo to build (gcc-go-tools conflicts with go).
Also, since gccgo is not a multi-compiler, we need to override GCCGO
to get cross-builds. The gccgo for target is always installed, as
it's a part of our cross-toolchains.
