Subject: or1k: add .note.GNU-stack section on linux
X-Git-Tag: releases/gcc-14.3.0~668
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f690bd46da8d6b92d3d3eb8a276b2e35b9f6034b;p=thirdparty%2Fgcc.git

or1k: add .note.GNU-stack section on linux

In the OpenRISC build we get the following warning:

    ld: warning: __modsi3_s.o: missing .note.GNU-stack section implies executable stack
    ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker

Fix this by adding a .note.GNU-stack to indicate the stack does not need to be
executable for the lib1funcs.

Note, this is also needed for the upcoming glibc 2.41.
