[Buildroot] [PATCH] package/physfs: needs threads support

[Romain Naour]

When physfs is build for a Linux system the PHYSFS_PLATFORM_POSIX
(which enable code that use pthread_*()) symbol must defined,
so threads support is required.
The physfs build system used by the previous version didn't correctly
set PHYSFS_PLATFORM_POSIX for system without pthread support.

Add pthread dependency.
