Trick to get a proper backtrace, I added a breakpoint on

This is because under the hood liblz.so could not be loaded (but the
actual error is silently swallowed):
--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,m(lzlib)
scheme@(lzlib)> (lzlib-procedure int "LZ_decompress_open" '())
$1 = #f
scheme@(lzlib)> %liblz
$2 = "liblz"
scheme@(lzlib)> (dynamic-link %liblz)

Entering a new prompt. Type `,bt' for a backtrace or `,q' to continue.

--8<---------------cut here---------------end--------------->8---
Compare with a native build of guile-lzlib on GNU/Linux:
--8<---------------cut here---------------start------------->8---
scheme@(lzlib)> %liblz
$2 = "/gnu/store/jqr5bz89gfwhxcndnhq333dyclvkq7ws-lzlib-1.11/lib/liblz"
--8<---------------cut here---------------end--------------->8---
Indeed, the cross-compilation build log shows:
--8<---------------cut here---------------start------------->8---
checking dependency style of i586-pc-gnu-gcc... none
checking lzlib's file name...
--8<---------------cut here---------------end--------------->8---

Hey Ludo,

Oh, I guess the same goes for guile-zlib and all cross-compilation
targets. I'll have a look later on.
Thanks,
Mathieu

Fixed in Guile-lzlib here:
https://notabug.org/guile-lzlib/guile-lzlib/commit/82576e34b4870b8977e131a40831219f8c1ea521
Guile-zlib doesn’t have this problem because it uses pkg-config to
determine LIBZ_LIBDIR.
When you feel like it, we can have a .2 release of Guile-lzlib with this
fix.
Thanks,
Ludo’.
