# Meson's Python module doesn't support crosscompiling,
2+
# and python dependencies may be another potential hurdle.
3+
# There might also be a need to run runtime tests during configure time.
4+
#
5+
# The recommended practice is to rely on Docker to provide the x86_64 crosscompile toolchain,
6+
# enabling native execution via binfmt.
7+
#
8+
# In simpler terms, everything except the crosscompile toolchain will be emulated.
