[avr-libc-dev] New include sys/types?

[Andy H]

Would it be possible for libc to have sys/types.h file?
There an annoying failure in gcc testsuite whenever this is included and 
I'd rather no skip or xfail the tests.
Its used to pick up uClibc symbol, otherwise its not needed.

File can be blank or just define size_t - as that appears to be only 
relevant bit for AVR.
