[gentoo-dev] [PATCH 2/2] multilib.eclass: populate READELF, bug #725304

[Sergei Trofimovich]

For both multilib and non-multilib profiles binutils provides
tools with native CHOST prefix only. For example on amd64 there
is only 'x86_64-pc-linux-gnu-readelf' and 'readelf'.

meson build system uses 'readelf' or $READELF binaries
and relies on meson.eclass to populate READELF.

The change overrides READELF and friends to 'x86_64-pc-linux-gnu-readelf'
for multilib setup similar to other environment variables.

Tested on net-libs/gssdp package.
