Started with r218397. 
HJ, it looks like this is now the intended behavior.

If you use -fpie, you should use -pie.
If you use -shared, you should use -fpic.

-shared was used for demonstration purpose only.
Same issue with -pie:

 % gcc -O2 -pie nscd.i -fPIE
/usr/lib/x86_64-linux-gnu/Scrt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
/home/trippels/bin/ld: /home/trippels/tmp/ccZF5sOU.o: relocation R_X86_64_PC32
against undefined symbol `program_invocation_name@@GLIBC_2.2.5' can not be used
when making a shared object; recompile with -fPIC

Does -fuse-ld=gold work?

Do you use the same ld to build GCC and glic?
If yes, please open a binutils bug and I
will fix it next week.

Please open a binutils bug and assign it
