[Buildroot] glib 2.40 on xtensa

[Thomas Petazzoni]

Baruch, Max,

We have recently update glib to version 2.40, and this is causing
issues on Xtensa:

  http://autobuild.buildroot.org/results/a1a/a1a1f97a2c54ba4f7f7e44cc094a55bd23ca0aa0/build-end.log

  CC       gspawn.lo
gthread-posix.c: In function 'g_cond_impl_new':
gthread-posix.c:648:2: error: #error Cannot support GCond on your platform.
 #error Cannot support GCond on your platform.
  ^
gthread-posix.c: In function 'g_cond_wait_until':
gthread-posix.c:896:2: error: #error Cannot support GCond on your platform.
 #error Cannot support GCond on your platform.
  ^
gthread-posix.c:859:19: warning: unused variable 'ts' [-Wunused-variable]
   struct timespec ts;
                   ^

Could you have a look and see what can be done to fix this problem?

Thanks!

Thomas
