[libgpg-error PATCHv2 0/2] Fix build without pthreads

[Yann E. MORIN]

Building libgpgp-error without threads is currently broken because some
files unconditionally #include <pthread.h> even if ./configure decided
threads were not available.

The first patch in the series fixes that.

Finally, tests are sometimes unneeded, especially on embedded devices.

The second patch adds an option to disable building tests.
