System

xuname: Void 5.15.41_1 x86_64-musl GenuineIntel notuptodate rFFFF
package: mdocml-1.14.6_3

Expected behavior

man uses less as the default pager. (The mdocml package has less as a dependency so less should always be installed with man on a Void Linux system)

Actual behavior

man uses more as the default pager.

Steps to reproduce the behavior

check out latest version of void-packages repo
crossbuild mdocml (for instance with ./xbps-src -a armv5tel-musl pkg mdocml
install mdocml on target device
open a man page (for instance man man)

Notes

I think this happens because although less is a build dependency of mdocml, the configure script for mandoc tries to run less to check whether it is present, but the cross version gets installed in usr/arm-linux-musleabi/bin, which isn't in PATH (and probably wouldn't run anyway being a non-native binary).

I figured out what was going on by running xbps-src -a armv5tel-musl configure mdocml, and looking at masterdir/builddir/mandoc*/config.log. I also verified that the same thing happened when cross-compiling for different targets (and different architectures).

I'm not sure of the right way to fix this, setting BINM_PAGER in configure.local would probably do the job, but maybe there is a more standard way of fixing this sort of problem?

hostmakedepends="less" solves this

Looks like there are a lot of execution failures on cross:
