stat() synthesized path-hash inodes for regular files but left
st_ino = 0 for directories. GCC's include-path setup deduplicates
directories by (st_dev, st_ino), so every directory on MontaukOS
compared equal and cc1plus silently dropped all C++ include dirs
except the first - <iostream> resolved but the target-specific
bits/c++config.h directory was gone. Directories now get the same
path-hash inodes as files. (Different spellings of one directory
hash differently; the harmless direction - a dir may be searched
twice, never dropped.)
Native GCC relinked against the fixed libc.
