Oops, this caused two link errors in a testdir of all modules:
gcc -ftrapv -Wno-error -g -O2 -L/media/develdata/devel/inst-x86_64-64/lib
-rdynamic -o test-execute-child test-execute-child.o -lm -lm -lm -lm -lm -lm
-lm -lm -lm -lm -lm
/usr/bin/ld: test-execute-child.o: in function `main':
/media/develdata/devel/GNULIB/testdir-all/build-64/gltests/../../gltests/test-execute-child.c:243:

Fixed as follows.
