Alexey Brodkin b833f45259 gcc: Make it aware of Newlib nano IO feature
Even though GCC as a compiler has nothing to do with a C library
being used it still makes sense to know about Newlib's compact
implementation of IO functions:

 * For targets like MSP430 which require to have such a tuned
   Newlib if "-mtiny-printf" is passed to the GCC's command-line [1]

 * For correct compilation of the following GCC's own DejaGnu tests [2]:
     - gcc/testsuite/gcc.c-torture/execute/920501-8.c
     - gcc/testsuite/gcc.c-torture/execute/930513-1.c
     - gcc/testsuite/gcc.dg/torture/builtin-sprintf.c
     - gcc/testsuite/gcc.c-torture/execute/ieee/920810-1.x

[2] https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=571bbd0d48d5872eacbd0b681fce6e1ae754520b

So we add that missing cross-dependency now.
