Don't be surprised if the CFLAGS are an empty string if you're installing

CFLAGS is empty on my Ubuntu 13 desktop. What does seem to work is
running 'pkg-config libssh2 --libs' and scan for '-lgcrypt' / '-lcrypto'.
It sounds like in practice you have extra initialization required for
re-entrant use - can you explain what that is? My feeling is that libssh2
should do this for you.
It's needed to set up the crypto library for multithreaded use. One
needs to set the proper call-back routines in libcrypto and libgcrypt,
or crashes will occur.
Is it libssh2's job to set up libcrypto/libgcrypt? libssh2 -could- do
so, but doing so could clash with other uses of the same crypto lib by
the program, so it'd have to be optional. Also, multithreading init code
requires a dependency on libpthread (and/or other threading libraries)
to be able to create the required mutexes etc.
