- adds several config-options to allow for turning off certain features
like o UCLIBC_HAS_GNU_ERROR o UCLIBC_HAS_BSD_ERR o UCLIBC_HAS_PTY o UCLIBC_HAS_GETPT (1) o UCLIBC_SYSCALL_STUBS o UCLIBC_SYSCALL_STUB_WARNING o UCLIBC_LINUX_SPECIFIC (2) o UCLIBC_BSD_SPECIFIC (3) o UCLIBC_NTP_LEGACY (4) o UCLIBC_SV4_DEPRECATED (5) o UCLIBC_HAVE_REALTIME (6) o UCLIBC_HAVE_ADVANCED_REALTIME (7) o UCLIBC_HAVE_EPOLL (8) o UCLIBC_HAVE_XATTR (9) o UCLIBC_HAVE_PROFILING (10) (1) make non-standard getpt optional and implement standard posix_openpt (2) fstatfs(), inotify_*(), ioperm(), iopl(), madvise(), modify_ldt(), personality() ppoll(), setresuid() (3) mincore(), getdomainname(), setdomainname() (4) ntp_adjtime(), ntp_gettime() aliases (5) ustat() [use statfs(2) in your code instead] (6) All marked as "(REALTIME)" in SUSv3 (7) All marked as "(ADVANCED REALTIME)" in SUSv3 (8) epoll_create(), epoll_ctl(), epoll_wait() (9) all Extended Attributes (10) helpers for gcc's -finstrument-functions - Fixes _dl_exit() - Implements sleep(3) for !UCLIBC_HAVE_REALTIME - Implements usleep(3) for !UCLIBC_HAVE_REALTIME - adds #warning about incorrect posix_fadvise{,64}() - removes unused and unwanted uselib() Net outcome is that an allnoconfig with HAVE_SHARED is now about 88k instead of formerly 130k.
