ld conflict between -r and --gc-sections


I was trying to add per function sections on our x86 BSP linking.
This is the only target which I saw any issue mixing -r and
--gc-sections. Each of our BSPs has its own linker script so
there could be something amiss with this one.

i386-rtems4.12-gcc --pipe -B../../../../../.././lib/ -B../../../../../.././pc386/lib/ -specs bsp_specs -qrtems -mtune=i386 -O2 -g -ffunction-sections -fdata-sections -Wall -Wmissing-prototypes -Wimplicit-function-declaration -Wstrict-prototypes -Wnested-externs -qnolinkcmds -nostdlib -r -Wl,--gc-sections -Wl,-Ttext,0x00100000 -o ne2000.rel ne2000_rel-ne2000.o
/data/home/joel/rtems-4.11-work/tools/4.12/bin/../lib/gcc/i386-rtems4.12/6.0.0/../../../../i386-rtems4.12/bin/ld: gc-sections requires either an entry or an undefined symbol
collect2: error: ld returned 1 exit status

Is this an x86 specific issue? Or is there something I
need to tweak in our linker script?

Any other ideas?
