Subject: [PATCH] linux-user: ARM: Ignore immediate value for svc in thumb mode

When running in thumb mode, Linux doesn't evaluate the immediate value
of the svc instruction, but instead just always assumes the syscall number
to be in r7.

This fixes executing go_bootstrap while building go for me.
