Undefined reference within static library, although the function is there - c++

Question

I try to compile QDP++ C++ library using the Intel 17 compiler and Intel MPI on an Intel Xeon supercomputer. The dependency QMP C library has already been compiled with that compiler (mpiicc), there were no compilation errors.
When trying to configure QDP++, I get this error from the Intel compiler:
~/local-jureca/lib/libqmp.a(QMP_init.o): In function `QMP_comm_get_allocated':
QMP_init.c:(.text+0x55): undefined reference to `QMP_abort_mpi(int)'
And this from GCC 5.4:
~/local-jureca/lib/libqmp.a(QMP_init.o):QMP_init.c:function QMP_comm_get_allocated: error: undefined reference to 'QMP_abort_mpi(int)'
So it is an actual problem and not just something that the Intel C++ with MPI compiler cannot do.
The output of nm ~/local-jureca/lib/libqmp.a contains this stanza where QMP_comm_get_allocated resides in.

Another stanza contains the function QMP_abort_mpi which supposedly cannot be found:
QMP_init_mpi.o:
U malloc
U MPI_Abort
U MPI_Comm_dup
U MPI_Comm_rank
U MPI_Comm_size

0000000000000020 T QMP_init_machine_mpi
U QMP_machine
The relevant output of `configure is:
configure: Parscalar build! Checking for QMP
checking for qmp-config... ~/local-jureca/bin/qmp-config
configure: Found QMP configuration program ~/local-jureca/bin/qmp-config
configure: QMP compile flags: -I~/local-jureca/include

configure: error: Cannot compile/link a basic QMP C++ program!
Check QMP_CFLAGS, QMP_LDFLAGS, QMP_LIBS.
So it seems to find the library just fine.
In the config.log a little larger chunk is this:

I have replaced the absolute path to my home directory with ~ because the actual path is not interesting.
What happens here? And how can I go about fixing it?
Update 1
This is part of the make output for QMP. It seems to be compiled with mpiicc which is a C (not C++) compiler:
depbase=`echo mpi/QMP_topology_mpi.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
/usr/local/software/jureca/Stages/2016b/software/impi/2017.0.098-iccifort-2017.0.098-GCC-5.4.0/bin64/mpiicc -DHAVE_CONFIG_H -I. -I../include -I../include -O2 -Wall -fopenmp -MT mpi/QMP_topology_mpi.o -MD -MP -MF $depbase.Tpo -c -o mpi/QMP_topology_mpi.o mpi/QMP_topology_mpi.c &&\
mv -f $depbase.Tpo $depbase.Po
And then the static library is linked together from the various units:
rm -f libqmp.a
