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)> (dynamic-link %liblz)

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---
