./load envdir unix.a byte.a
/usr/bin/ld: errno: TLS definition in /lib64/libc.so.6 section .tbss mismatches non-TLS reference in envdir.o
/lib64/libc.so.6: could not read symbols: Bad value
collect2: error: ld returned 1 exit status

The fix is quite simple: explicitly add #include <errno.h> to the offending file and then recompile.
