| Subject: [PATCH] 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: |
