;; Hack for proper PIE run of the testsuite.
;;=fedoratest
make check//unix/-fPIE/-pie RUNTESTFLAGS=solib-display.exp
gcc -fpic -c -fPIE -pie -o x.o x.c
/usr/lib/gcc/x86_64-redhat-linux/4.6.1/../../../../lib64/Scrt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
=> Change the order for overrides.
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.
