Sorry, that's what I was trying to show with the last example. The
Linux gdb from CentOS running under the Linuxulator gives:

# gdb -q ./testcases/bin/mremap05 mremap05.core
Reading symbols from /opt/ltp/testcases/bin/mremap05...done.

warning: A handler for the OS ABI "FreeBSD ELF" is not built into this
configuration
of GDB.  Attempting to continue with the default i386:x86-64 settings.

"/opt/ltp/mremap05.core": no core file handler recognizes format
