To avoid populating the cross-file with non existing compilers,
we tie them to /bin/false.
As explained by @eliebrokeit on the meson IRC channel:
If you don't have one [a compiler] defined, cross builds won't try
to autodetect one, IIRC...
... however setting it to /bin/false will result in it detecting
that that doesn't work
I guess the safest bet is to deliberately poison it with /bin/false
So there we go.

# Meson package infrastructure
|
|
#
|
|
# This file implements an infrastructure that eases development of
|
|
# package .mk files for Meson packages. It should be used for all
|
|
# packages that use Meson as their build system.
|
|
#
|
|
# See the Buildroot documentation for details on the usage of this
|
|
# infrastructure
|
|
#
|
|
# In terms of implementation, this Meson infrastructure requires
|
|
# the .mk file to only specify metadata information about the
|
|
# package: name, version, download URL, etc.
|
|
#
|
|
# We still allow the package .mk file to override what the different
|
|
# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
|
|
# already defined, it is used as the list of commands to perform to
|
|
# build the package, instead of the default Meson behaviour. The
|
|
# package can also define some post operation hooks.
|
|
