--- Comment #2 from zenith432 at users dot sourceforge.net ---
Update:
1) This bit was being output from its inception in commit 7898495.
2) Up until commit a6fd92b, the bit was being masked by objdump and objcopy, so
the workaround was available. Since commit a6fd92b, the bit is not longer
masked, but causes both these tools to stop with an error message. readelf -r
can display the bit.
3) The -q option is for leaving section relocs in the object file for
post-processing tools. Outputting this bit can break any post-processing tool
like it breaks objdump and objcopy.
-q
--emit-relocs
Leave relocation sections and contents in fully linked executables.
Post link analysis and optimization tools may need this information
in order to perform correct modifications of executables. This
results in larger executables.
This option is currently only supported on ELF platforms.
4) Please fix this for 2.31.
5) Following is a patch that fixes this
