[Arnout:
 - Indent hash file with two spaces.
 - Bump to 1.7.3 to fix build failure with recent GCC.
 - Get from github instead of PyPI.
 - Add host-meson and host-python-pythran dependencies.
 - Properly propagate Config.in dependencies.
 - Correct usage of BR2_INSTALL_LIBSTDCPP symbol.
 - Remove F77, no longer used.

This is v9 but changed so much that it warrants starting anew :-)

The build still fails in several ways that are due to broken
cross-compilation. A few examples:

compile options: '-c'
extra options: '-march=native'
CCompilerOpt.dist_test[581] : CCompilerOpt._dist_test_spawn[716] : Command (.../host/bin/aarch64-linux-gcc -Wno-unused-result -Wsign-compare -DNDEBUG ... -fPIC -c .../host/lib/python3.10/site-packages/numpy/distutils/checks/test_flags.c -o /tmp/.../distutils/checks/test_flags.o -MMD -MF /tmp/.../numpy/distutils/checks/test_flags.o.d -march=native) failed with exit status 1 output ->
cc1: error: unknown value ‘native’ for ‘-march’

(more errors like this when trying to use SSE flags on ARM)

compile options: '-I.../host/lib/python3.10/site-packages/numpy/core/include -Ibuild/src.linux-x86_64-3.10/numpy/distutils/include -c
(i.e. using host includes for target build)
