Yes, It works in the binutils-2.17 for function.  

Patch: http://sourceware.org/ml/binutils/2006-02/msg00366.html

LD:

In order to fix the --gc-sections bug I have added the required KEEP() 
statements in the linker script for avr.
The contents of .data* , .rodata and .rodata* are now also linked into 
the .data output section so that gcc could be used with the -fdata-sections 
switch.

........
 * ld/scripttempl/avr.sc:
add *(.jumptables) *(.lowtext), add KEEP() directives
add *(.data*) *(.rodata) and *(.rodata*) and *(.bss*) to .data and .bss
output sections.
