libiscsi: only build the test tool and ld-iscsi if we have shared libs

Backporting an upstream patch to fix a failure when doing a static
build:

/br/output/host/usr/bin/mipsel-ctng-linux-uclibc-gcc -shared -o
ld_iscsi.so ld_iscsi.o -ldl
/br/output/host/opt/ext-toolchain/bin/../lib/gcc/mipsel-ctng-linux-uclibc/4.8.2/../../../../mipsel-ctng-linux-uclibc/bin/ld:
ld_iscsi.o: relocation R_MIPS_HI16 against `__gnu_local_gp' can not be
used when making a shared object; recompile with -fPIC
ld_iscsi.o: could not read symbols: Bad value
collect2: error: ld returned 1 exit status
