/bin/sh: Argument list too long

I tried building binutils-2.25 in a qemu chroot and I got the following error during the build process:

/bin/sh: Argument list too long

Google wasn’t helpful. So I looked at the code for qemu-2.2.0, which is where my static qemu binary comes from. At some point I stumbled on this line in linux-user/qemu.h:

#define MAX_ARG_PAGES 33

I changed that 33 to a 64, rebuilt, replaced the approriate static binary in my chroot, and the error went away.
