Best way to set up a build environment in /compat/linux

[Sijmen J. Mulder]

Hi all,

With Linux emulation enabled I can successfully run a statically linked 
Linux binary that I built on an Ubuntu system (with musl libc).

I'd like to install the necessary development tools (compilers, 
libraries, headers, etc) in the Linux compat environment. It appears 
that linux_base-c6 does not contain a package manager (yum or dnf). 
What's the best way to install these tools? Did people have success 
installing and using a package manager, or should I manually download 
RPMs, or even compile from source?

The wiki has this guide: https://wiki.freebsd.org/VIMAGE/Linux/CentOS55 
but it's rather old and I couldn't learn much from it.

Alternatively I'd also be interested in cross compiling to Linux 
directly from FreeBSD, if that's more practical. Still I'd need the 
headers and libraries.

Cheers,
Sijmen
