You need to propagate the e2fsprogs dependency here.

The code isn't really clear as to whether it is GPLv2 or GPLv2+. The
COPYING file is the text of GPLv2, but the comment headers in the code
don't explicit whether it's GPLv2 only, or GPLv2+. I guess in a case
like this, we should assume it's GPLv2, as you did.

So you need a dependency on BR2_TOOLCHAIN_HAS_THREADS as well.

I know (from IRC discussion) you used this instead of the default "make
install" to not install man pages. But that's not needed: provided
BR2_HAVE_DOCUMENTATION is disabled (which is almost always the case
since this option is deprecated), then Buildroot automatically removes
man pages. So unless using "make install" causes a problem, we'd prefer
to not use a specific <pkg>_INSTALL_TARGET_OPT, and let Buildroot
remove the man pages.

Best regards,

Thomas
