On Ubuntu:
1. mount the RaspberryPi SD card image partition 2 on /mnt
decide a better directory later
2. Run the script
#!/bin/sh
##
## build the object file
arm-linux-gnueabihf-gcc-4.6 -c \
-nostdlib -mcpu=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard -marm -Wl,-t \
hello.c -o helloc.o
##
## link
arm-linux-gnueabihf-gcc-4.6 -o helloc helloc.o \
-nostdlib -mcpu=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard \
-marm -Wl,-t \
/mnt/usr/lib/arm-linux-gnueabihf/crt1.o \
/mnt/usr/lib/arm-linux-gnueabihf/crti.o \
/mnt/usr/lib/gcc/arm-linux-gnueabihf/4.6/crtbegin.o \
/mnt/lib/arm-linux-gnueabihf/libgcc_s.so.1 \
/mnt/lib/arm-linux-gnueabihf/libc.so.6 \
/mnt/usr/lib/arm-linux-gnueabihf/libc_nonshared.a \
/mnt/lib/arm-linux-gnueabihf/ld-linux-armhf.so.3 \
/mnt/usr/lib/gcc/arm-linux-gnueabihf/4.6/crtend.o \
/mnt/usr/lib/arm-linux-gnueabihf/crtn.o \
/mnt/lib/arm-linux-gnueabihf/libm.so.6
This produces an image that will execute on the Raspberry Pi.
There seems to be a problem with either the crtxxx.o files or the libs.
Where do I file a bug report?

GCC bug reports go to http://gcc.gnu.org/bugs/ but if the problem is
the library paths on Ubuntu it's a known issue that should fixed in
current sources.

The problem is not the paths, it is the files. I substituted the
RaspberryPi files by using -nostdlib and explicit listing the files on
the command line,
diff says the crtxxx.o files on ubuntu are not the same as the same path
file on RaspberryPi.
The libs may also be not usable.
diff says /usr/lib/gcc/arm-linux-gnueabihf/4.6/libgcc_s.so.1 on ubuntu
is not the same as the same path file on RaspberryPi.
