Just ignore it.  The "bogomips" value is bogus, as the name
suggests.  It's the result of a very simple timer calibration
loop in the Linux kernel.  The BSDs don't have the same loop,
so they don't know the bogomips value.

Most of these are probably caused by tools that don't exist
under /compat/linux, so the BSD variant is used, which might
behave differently from the Linux/GNU version.

That's probably SIGABRT.  Looks like a non-Linux-ELF file was
executed with the Linux linker.

The Linuxulator doesn't have an awk binary, so the DragonFly
binary was used, which is the so-called "one true awk", which
is missing a lot of features that GNU awk has.  So I'm not
surprised that LTP fails here.

You could try to install GNU awk (gawk) and make LTP use it.

Probably.

The "which" command (whether shell-builtin or /usr/bin/which
doesn't matter) simply looks at the PATH environment variable:
It opens every directory, one after another, and looks for
the binary.  It is first found in /usr/pkg/bin.  Note that
the linuxulator doesn't redirect the directory because
/compat/linux/usr/pkg/bin doesn't exist.  So the "which"
command prints /usr/pkg/bin/bash.  The same happens when
you type "/usr/pkg/bin/bash" because this path doesn't exist
under /compat/linux, so you'll get the DFly bash.

However, when you only type "bash" at the Linux bash prompt,
it simply forks a subshell of itself, so you get the Linux
bash again.
