errno definition broken in non-threaded code

[Cristiano Ghirardi]

Hi,
I'm justing porting pppd on a custom Nios2 board and the program crash at
run-time.
I got crazy to understant what was wrong after some cleanup (fork mainly)
and I discovered
that the program crashed in the following line of code:

err = errno;

I'm making a relocable object and a custom linker map and elf2flt to produce
an BFLT executable.
I put #include <errno.h> and in uClibc I'm usinglinuxthreads.old.
After commenting out that line of code everything is working fine.
Best Regards
