lib/Makefile and drivers/net/Makefile includes sharelib.mk _always_, this flag is to include sharelib.mk only when we are compiling combined library.
Previously this inclusion was not problem because there was not common variable, now we start using common CPU_LDFLAGS variable and sharedlib.mk shouldn't included when not compiling for combined lib.

Thanks, I will fix this and send a new patch, I assume I can rely on "*_version.map" naming convention.
