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
[1] https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=02afb6a9321fbfb435452636cedc2cd43f0c4fd2
[2] https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=571bbd0d48d5872eacbd0b681fce6e1ae754520b
So we add that missing cross-dependency now.
