From af0dbc540b4acc54ec9f4d1064402f75edb5a7ca Mon Sep 17 00:00:00 2001

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.
