Arnd Bergmann fa3866b67d kallsyms: ignore ARMv4 thunks along with others ...

[ Upstream commit a951884d82 ]

lld is now able to build ARMv4 and ARMv4T kernels, which means it can
generate thunks for those (__ARMv4PILongThunk_*, __ARMv4PILongBXThunk_*)
that can interfere with kallsyms table generation since they do not get
ignore like the corresponding ARMv5+ ones are:

Inconsistent kallsyms data
Try "make KALLSYMS_EXTRA_PASS=1" as a workaround

Replace the hardcoded list of thunk symbols with a more general regex that
covers this one along with future symbols that follow the same pattern.

Fixes: 5eb6e28043 ("ARM: 9289/1: Allow pre-ARMv5 builds with ld.lld 16.0.0 and newer")
Fixes: efe6e30680 ("kallsyms: fix nonconverging kallsyms table with lld")
