'make check' fails on '08_nodeflib'

Hello,

when I try to run tests, '08_nodeflib' fails:

/tmp/guix-build-libtree-3.1.1.drv-0/source/tests/08_nodeflib$ make check
echo 'int f(){return 1;}' | cc -z nodefaultlib -Wl,--no-as-needed -shared -Wl,-soname,lib_nodefaultlib.so -o lib_nodefaultlib.so -x c -
echo 'int g(){return 1;}' | cc -Wl,--no-as-needed -shared -Wl,-soname,lib_defaultlib.so -o lib_defaultlib.so -x c -
echo 'extern int f(); extern int g(); int main(){return f() + g();}' | cc -z nodefaultlib -o exe_a -Wl,--enable-new-dtags '-Wl,-rpath,$ORIGIN' -x c - -L. -l_nodefaultlib -l_defaultlib
echo 'extern int g(); int main(){return g();}' | cc -z nodefaultlib -o exe_b -Wl,--disable-new-dtags '-Wl,-rpath,$ORIGIN' -x c - -L. -l_defaultlib
! ../../libtree -vvv exe_a # should likely not find libc

make: *** [Makefile:33: check] Error 1

As far as I can see, the issue is that libtree finds libc when it shouldn't. I'm using the following compiler and linker versions:

$ gcc --version

The tests ran on Ubuntu 20.04.4 LTS

Thanks, avp
