Alexey Neyman 43c303c946 libc/*.sh: handle combinations of multilib root/dir. ... Install startfiles for libc variants into the most specific combination (suffixed sysroot, if applicable + suffixed multi-os dir, if applicable). Install headers once in every suffixed sysroot (although it seems that GCC picks up headers from top-level sysroot, GCC manual claims that sysroot suffix affects headers search path). In uClibc, this requires a better sanitization of the directory: it creates symlinks from {sysroot}/usr/lib/{multi_os_dir} to {sysroot}/lib/{multi_os_dir} and to do so, it counts the number of path components in the libdir. This breaks if one of such components is `..' - symlinks contain an extra `../..' then. Since such sanitization had to be implemented anyway, use it in other places to print more sensible directory names. Also, fix the description of configure --host/--target per musl's configure help message (and its actual code). Signed-off-by: Alexey Neyman <stilor@att.net>		2016-08-23 11:00:27 -07:00
