Not that I recommend this as a fix for the original problem btw. :-) Just FYI. As Kito says, the easiest way of treating a static link like a shared one is to use --whole-archive -lfoo --no-whole-archive. If the library is compiled with -ffunction-sections -fdata-sections, --gc-sections should remove the unnecessary code.
