Commit Message

Khem Raj Sept. 28, 2026, 5 a.m. UTC 
musl is built with -fno-asynchronous-unwind-tables, so libc.so carries
almost no .eh_frame and its CFI only lives in .debug_frame. Without it the
unwinder cannot get out of abort () and run-backtrace-dwarf.sh fails with
"No DWARF information found". Add musl-dbg to the ptest dependencies, like
glibc-dbg for glibc.

run-backtrace-native-core.sh then unwinds the thread correctly but loops on
musl's __clone, which has no end-of-stack CFI. That is the same reason
run-backtrace-native.sh is already an expected failure on musl, so mark the
core variant as one too.
