Can you tell me what that flag might be?

If I can't cross compile, then as I see it, I have two options: Either
I can compile on the device itself, or I can emulate an ARM CPU on my
x86 machine and pretend that it's compiling on the real thing.
The former is currently blocked by disk space issues: after installing
GCC and company on the device, there is insufficient disk space
remaining to actually compile ECL. I can try to get enough room, but I
don't know how successful I can be in this.
When I try the latter method, using qemu-arm to emulate the machine, I
get the following error during compilation:
;;; Note: Invoking external command:
In function `_start':../sysdeps/arm/elf/start.S:99: undefined
reference to `main'
collect2: ld returned 1 exit status
LAMBDA: Too many arguments to function CONTINUE.
;;; arm-linux-gnueabi-gcc -o

TOP-LEVEL. File: #P"/home/elliott/src/ecl-9.1.0/src/lsp/top.lsp" (Form
#26)No restarts available.
Finally, if I can emulate the CPU, is there any way I can configure
with emulation, then use the results from that configure to try and
set up cross compilation again?
Thanks for your help.
