Since ld may depend on libctf (if present), and libctf may be relinked
by the installation process, libctf must be installed before ld is,
or the relink may fail if it calls on symbols or symbol versions that do
not exist in any libctf already present on the system. (If none is
present, the copy in the build tree will be automatically used, but
if one *is* present, it may take precedence and break things.)
(This is a maybe- dependency, so it will work even if libctf is
disabled.)
ChangeLog

* Makefile.def: Add install-libctf dependency to install-ld.
* Makefile.in: Regenerated.
A case of inst->next being uninitialised.

is initialised.

The DWARF5 spec does indeed explicitly say: "A bounded range entry whose
beginning and ending address offsets are equal (including zero) indicates
an empty range and may be ignored."
Since arange_add already ignores empty ranges, remove the whole check
which is equivalent to the check plus explicit continue.

number tables.

Local symbols are of course supposed to be defined by their object
file, but in other cases a local symbol is promoted to global by gas
if undefined and referenced. This patch stops gas wrongly replacing a
local undefined symbol with the undefined section symbol, resulting in
a .reloc undefined local symbol being emitted as global.
