Uwe Hermann af61aaef21 Minor ld script changes.
Add wildcards to the input section names.
This fixes the script for use with the "-ffunction-sections
-fdata-sections -Wl,--gc-sections" options when compiling/linking.

Also, discard the .eh_frame section. This section is emitted by GCC 4.4,
but not 4.5. Discarding it doesn't appear to break anything. I suspect this is
used for C++ exception implementation.

I found this to be a problem when building with GCC 4.4 (arm-elf),
because the USB DFU demo exceeded the 8k I allowed for it.

Thanks to Gareth McMullin <gareth@blacksphere.co.nz> for the patch.
