Waf has a utility function ('lib64' in waflib/Utils.py) which
either returns an empty string or '64' depending on if either of
the paths '/usr/lib64' or '/usr/local/lib64' exist. Then, the
build system itself decides its default LIBDIR to be either
/usr/lib or /usr/lib64 depending on the result of that function,
except when libdir is passed explicitly.
We don't allow lib64 in our packages. We do have the /usr/lib64
path as that is a symlink. Therefore, do not ever allow waf to
configure the path that way.
This adds the build profiles for ppc64 targets as well as
modifications in other parts of the infra.
These targets are supported:
- ppc64le (glibc little endian elfv2)
- ppc64le-musl (musl little endian)
- ppc64-musl (musl big endian)
ELFv1 targets are explicitly not supported at this point.
Big endian musl supports ppc 970 or newer, while little endian
targets are set to a generic powerpc64le which effectively means
POWER8 and newer. Tuning is always set for POWER9, which is the
most likely target hardware. We also make sure AltiVec is always
on, because it is supported on all hardware we target.

Adds support for Go modules by detecting a go.mod file and, if
available, using it. In addition, to continue supporting vendoring (and
avoid the need for git on all module builds), if a package includes
a vendor directory, the module mode will switch to vendor mode if not
already set. This will use vendored source code for dependencies
instead of downloading that code again using the descriptions under
go.mod.
go_mod_mode=vendor also skips the go.sum check because nothing is
downloaded that isn't already verified, so this fixes packages with
vendored code that have checksum mismatches due to Go 1.11.4 module
checksum changes.

Closes: #6036 [via git-merge-pr]
PKG_CONFIG environment variable should point to the pkg-config executable
to be used to fetch dependencies that use 'native: true' (indicate to build
against host libraries not cross-compiled ones)
To meet those requirements we set an absolute path to the host
pkg-config since the relative path to pkg-config is taken by the
wrapper.
This currently requires a patch that is a milestone of meson-0.48 that
was generated by the issue:
