Severity: normal
Priority: P2

[...]
8. For a native linker on an ELF system, if the file
/etc/ld.so.conf exists, the list of directories found in that
file.
Actually, studying the code of ldelf.c, I understand that it is
<sysroot>/<prefix>/etc/ld.so.conf or <sysroot>/etc/ld.so.conf which is used.
Furthermore, if all that fails, it falls back to using the search path of the
ld script (or another search path, I am not sure: it uses the "search_head"
variable, which may be modified by using a pointer to it, so not easy to follow
statically). So I think the doco should have a point:
9. On an elf system, falls back to use the search path of....
