Unsure if this is actually common to all hardware, trying some other flavors as I write this, but on a gentoo aarch64-unknown-linux-gnu system emerging sys-fs/lvm2::musl with an aarch64-unknown-linux-musl cross-toolchain the build fails with undefined references to rpl_malloc and rpl_realloc A fix/workaround I've found is to set (either in the ebuild's src_configure or via pkg.env) ac_cv_func_malloc_0_nonnull=yes and ac_cv_func_realloc_0_nonnull=yes Unsure where such a fix should be made, either in sys-devel/crossdev's site files or maybe in the ebuild itself (I've seen it/similar hacks in a lot of in-tree ebuilds). Other info inbound as I un'fix' it and rerun builds to capture logs and such.

I guess it would help to see config.log if it's dependent on ./configure output. My guess would be that checking for GNU libc compatible malloc... no is a relevant piece.

Exact same failure on an x86_64-pc-linux-gnu->x86_64-pc-linux-musl cross

I'm indeed very tempted to just throw this in to crossdev or the profiles when using a known libc.

I was wondering why this had never been (much of) an issue for other places. It's because of the CHOST being slightly different for just some musl profiles. I'll fix it.

Sets ``` ac_cv_func_malloc_0_nonnull=yes ac_cv_func_realloc_0_nonnull=yes ``` ... to sort out flex and a bunch of other packages, like procps. I was wondering why this never seemed to come up when doing cross for other "standard" targets which we know work and are used often; the answer is that we never had the -musl suffix CHOSTs covered. (e.g. linux-gnu already has this set.)

(Ignore the last part, was confusing it w/ -gentoo- vendor part for some, point remains though)
