No rule to make target '.../check-abi-libcidn.out', needed by 'tests'. Stop.

[Andreas K. Huettel]

Hi, 

I'm trying to figure out why in our Gentoo builds the test fail consistently 
(since 2.22 at least, many arches) with something like

make  subdir=libidn -C libidn ..=../ tests
make[2]: Entering directory '/var/tmp/portage/sys-libs/glibc-2.26-r1/work/
glibc-2.26/libidn'
make[2]: *** No rule to make target '/var/tmp/portage/sys-libs/glibc-2.26-r1/
work/build-x86-x86_64-pc-linux-gnu-nptl/libidn/check-abi-libci
dn.out', needed by 'tests'.  Stop.
make[2]: Leaving directory '/var/tmp/portage/sys-libs/glibc-2.26-r1/work/
glibc-2.26/libidn'
make[1]: *** [Makefile:216: libidn/tests] Error 2
make[1]: Leaving directory '/var/tmp/portage/sys-libs/glibc-2.26-r1/work/
glibc-2.26'
make: *** [Makefile:9: check] Error 2

Any hints on how to debug this?

It may well be a Gentoo-specific error, but I can't see any of our 2-3 patches 
touch that area.

Thanks a lot in advance, 
Andreas
