ref-manual: Updates to ELF binary QA warning
Fixes [YOCTO #7630]
Apparently the text relocation being done here can cause runtime
performance issues. I documented a potential work-around for the
issue and provided a cross-reference link to an external site for
more general information about text relocation at runtime.
