nptl: Clear TLS area for static binaries.
busybox init checks it has pid 1, but getpid() returns another value when building busybox statically. This is because the corresponding area is not cleared when allocated (it is allocated with MAP_UNINITIALIZED, whose behavior depends on the Linux kernel's CONFIG_MMAP_ALLOW_UNINITIALIZED). This patch fixes the problem by explicitly clearing the memory area. * libpthread/nptl/sysdeps/generic/libc-tls.c (__libc_tls_setup): Clear tlsblock.
