Trying to compile hello world on openmoko neo freerunner fails

$ cat > hello.c <<EOF
#include <stdio.h>

int main(int argc, char *argv[]) {
    puts("Hello world");
    return 0;
}
EOF
$ /usr/lib/gcc-snapshot/bin/gcc -o hello hello.c
Illegal instruction

apparently since

Program received signal SIGILL, Illegal instruction.

0x9a54: ldr     r3, [r4, #8]
0x9a58: cmp     r3, #2  ; 0x2

tries to execute a BLX instruction which is not supported in ARMv4. ARM
architecture reference manual page 113, section A3.3 says that BLX
with register operand is only available in ARMv5 and above. Could
please consider compiling gcc-snapshot with support for also ARMv4
like the gcc-4.3 package does?
