buildsys: fix static configuration and building
In case of uClibc librt depends on libpthread. In particular
timer_create() function uses pthread_XXX(). That means in case of static
builds it's required to link not librt alone but together with libpthread. So
if checking timer_create function in librt fails, it is necessary to check if
timer_create function successfully links with "-lpthread".
That issues was spotted in Buldroot autobuilder failures:
