Diff below contains 3 things and is widely discussed with kirill@, and
gone through miod, but sending it here so other people get a chance to
chime in.
1) The report keyword results in an #error with newer gcc build system.
Simply removing the keyword suggested by kirill@.
2) LINK_SPEC is already defined in gcc itself and causes a lot of
redefine noise. Going for the gcc definition as suggested by kirill@.
3) upstream gcc has the same stack protector logic as was recently
fixed in base by miod@. This fixes similar build issues found with
gcc-16. Confirmed by miod@.
OK?
