rust-common.bbclass: rewrite toolchain wrappers in (native) python
librsvg on centos 7 and friends exhibits the same libtinfo leakage
problem, this time coming from the compiler and not the linker.
Simply covering the compiler by the existing C wrapper-of-wrapper
does not work, as rust-native builds put Important Stuff into
LD_LIBRARY_PATH and unsetting it breaks things badly.
Rather than try to figure out which combination of wrappers and
LD_LIBRARY_PATH settings works for which situation, or provide
some kind of sh-native, let's simply use python3-native for the
wrappers, which should insulate builds from the the host shell.
rust-native already depends on python3-native, so this does not
lengthen the builds.
This also reverts:
rust-common: Hack around LD_LIBRARY_PATH issues on centos7
(commit
63b1fd2226b5f146d6c853cc57417704df378438).
I'd also like to say boo to Red Hat (or GNU?) for breaking ABI
compatibility for stat() in glibc 2.33, we ended up sorting
this mess because of it.
