Bug#162576: libc6-dev: errno is a function call in non-threaded program

[<herbert@gondor.apana.org.au>]

Package: libc6-dev
Version: 2.2.5-14.3
Severity: minor

bits/errno.h defines errno to be a function call even when the application
has no need for threads at all.  This definition should be made conditional
so that non-threaded programs do not suffer the overhead of the function
call.
