QA Notice: Missing gen_usr_ldscript
   

If you have a shared library in /lib/ and a static library in /usr/lib/, but no linker script in /usr/lib/, then the toolchain will choose the incorrect version when linking. The system linker will find the static library first and not bother searching for a dynamic version. To overcome this, you need to use the gen_usr_ldscript function found in the toolchain-funcs.eclass. Refer to the man page for information on how to use it. See this bug report for some history on this issue.
