The buildroot patches have xtensa for the supported versions of binutils we use, and a few others that might help us keep away from host polution. Signed-off-by: Bryan Hundven <bryanhundven@gmail.com>

Subject: [PATCH] Fix xtensa ld segfault when linking linux modules
|
|
|
|
is_inconsistent_linkonce_section makes an assumption that section name
|
|
that starts with ".gnu.linkonce.prop." has one more dot in its suffix.
|
|
However gas generates such section name by insertion of "prop." right
|
|
after ".gnu.linkonce." part of the name of the original section. So, for
|
|
section named ".gnu.linkonce.this_module" corresponding property section
|
|
name does not satisfy the assumption. Such section names are common in
|
|
linux modules. This bug was exposed by the patch "a35d5e8 Fix alignment
|
|
for the first section frag on xtensa", that makes gas produce property
|
|
section for each section that has ".align" directive in it.
|
|
|
|
Use suffix that immediately follows ".gnu.linkonce.prop." when there are
|
|
no more dots following it.

ld/

|
* emultempl/xtensaelf.em (is_inconsistent_linkonce_section):
|
|
correctly handle missing dot in section name after
|
|
".gnu.linkonce.prop.".
