This symbol was causing a build failure with the new toolchain. It looks like it has always been wrong.

The main issue was checking for PIC rather than __PIC__.

Indeed, I also noticed this. I've made a similar/simpler patch but the system doesn't boot (init program is stuck after "Run /init as init process") Sadly, the system doesn't boot even with your patch. Have you successfully runtime tested uClibc-ng build with your patch? Best regards, Romain

Remove all PSEUDO_* macros and ther SYSCALL_ERROR_NAME macro as they are not needed by uclibc-ng, they are used in glibc for building up syscalls there, but not here.
