Dear stable maintainers,
Please consider cherry-picking c8a950d0d3b9 ("tools: Factor HOSTCC,
HOSTLD, HOSTAR definitions") to 5.10, 5.4 and 4.19. It fixes a problem
where the host tools set by the user could be ignored for
'prepare-objtool', and is needed on x86 to enable the ORC unwinder,
dynamic ftrace, etc. with LLVM=1 and a 'hermetic' toolchain
environment.
On 5.10.10 it cherry-picks cleanly. On 5.4.92 and 4.19.170 it
cherry-picks cleanly, besides 'tools/bpf/resolve_btfids/Makefile'
which was introduced after 5.8-rc2. (This file can be ignored.)
Thanks!
