internals: fix stripping host binaries

The gcc used by linaro has a version number specific to Linaro, but
identifies itself with its upstream version numbering scheme.

This breaks the strip in the finish step, because the actual gcc version
is not the same as the configured one (eg. 4.5.2 vs. linaro-4.5-2011.02-0).

     4 Attached is a patch to add __attribute__ ((noinline)) to
     5 call_gmon_start.
     6 
     7 Without this patch, the sec script that processed initfini.s removes a
     8 part of inlined call_gmon_start, causing undefined label errors.
     9 
    10 This patch solves the problem by forcing gcc not to inline
    11 call_gmon_start with __attribute__ ((noinline)).
    12 
    13 Tested by building for arm-none-lixux-gnueabi.  OK to apply?
