build fails with undefined reference to symbol pthread_rwlock_rwlock

[grawity]

Continuing from #15 since non-contributors cannot reopen a closed task and the thing still doesn't build. As mentioned in the last comment,

libdpe is using the function the linker is complaining about; see the calls to rwlock_wrlock() which are translated via preprocessor defines to pthread_rwlock_wrlock().

Indeed, libdpe/lock.h has this:

#define RWLOCK_CALL(call) \
    ({ int _err = pthread_rwlock_ ## call; assert_perror(_err); })
[...]
#define rwlock_wrlock(lock) RWLOCK_CALL(wrlock (&lock))

So it very much looks like pesign is trying to use the function directly, and so should -lpthread directly.

And yes, I see that libdpe/Makefile has LIBS=pthread. That seems to work fine for the shared library (libdpe.so), but pesign itself uses the static library (libdpe.a) and I don't believe static libs even have a place to record this kind of information?

Fixed in 0.112, thanks.
