[igt-dev] [PATCH v2 i-g-t] meson: Allow source location to be configurable

[Richard Purdie]

Hardcoding a build source path inside a binary when cross compiling isn't
appropriate and breaks build reproducibility. Allow the srcdir to be
specified by an optional configuration option to meson which can
be used to override with the correct path.
