+One has to also use -fPIC rather than -fPIE, -fPIC is stronger.
+
+The correct way would be:
+make check//unix RUNTESTFLAGS='CC_FOR_TARGET=gcc\ -fPIC\ -pie CXX_FOR_TARGET=g++\ -fPIC\ -pie solib-display.exp'
+
+But there is a problem with testsuite.unix non-unique subdir name and also
+a problem with make -j parallelization of the testsuite.
