Subject: [PATCH 4/6] configure.ac: fix __xmknod{,at} pointer argument
Switch default to assume * and not the absence of *.
On glibc 2.33+, there is no definition for these functions in header
files, so the compile test doesn't work. But, we can default to using
the pointer (as is the case with newer glibc), and use the header file
on older platforms to fail the test and use no pointer.

Subject: [PATCH 5/6] libfakeroot.c: fix fts_read and fts_children
Apply Debian patch from [0], since glibc is usually built without LFS.
__USE_LARGEFILE64 and FTSENT64 should be used anyway for proper support
of this, if needed. See [1] for more details.
