code coverage, ARM and C library

[Vladimir Prus]

Hello,
at the moment, when building gcc for arm-none-eabi with newlib as C library,
gcc decides that the C library is not available, sets inhibit_libc for 
compilations, and as result instead of real gcov support routines dummy 
functions are used.

There are two places where inhibit_libc is set

      - Configure code (which looks at --with-newlib and --with-headers)
      - Arm config bits, which set inhibit_libc unconditionally.

That hardcoding looks wrong -- there's nothing fundamentally preventing 
building arm toolchain with some C library. If I remove that hardcoding, and 
modify configure options appropriately, inhibit_libc is not set, gcc builds 
fine, and the code coverage works.

The patch is attached, OK?
