From: "Anthony G. Basile" <[email protected]> statfs() is a Linux-specific function. When building without UCLIBC_LINUX_SPECIFIC set, libc_hidden_proto(statfs) in include/sys/statfs.h is unmatched with libc_hidden_def(statfs) in libc/sysdeps/linux/common/statfs.c, leading to a compile error. This patch fixes this, as well as adds statfs() to the list of Linux-specific functions in extra/Configs/Config.in.
