GCC compilation options [message #24148]

Hi,

I've noticed that u++ doesn't force gcc to remove unused functions nor data, so binaries are usually bigger (comparing to MS compiler). So, my proposition is to add:
1. -ffunction-sections and -fdata-sections to compilation options for gcc
2. -Wl,--gc-sections to linker options

I know that "-ffunction-sections" is already used, but without --gc-sections it is useless.
