cc-gcc: the frontends are responsible for mkdir/chdir

The build dir are created depending on the host (host for that specific
backend, not host for the toolchain). Only the frontends know what host
this is, so only the frontends can create non-ambiguous dirs.

This patch is needed on newer uclibc becuase the uclibc header generation
yann@1045
     2
mechanism generates the sysnum.h properly NR_cacheflush is defined for ARM
yann@1045
     3
but there is no cachectl.h file which is exported to userspace. Strace 
yann@1045
     4
assumes that if SYS_cacheflush is defined than it icludes asm/cachectl.h
yann@1045
     5
which breaks the build for ARM now.
