[Buildroot] setserial fails to build (after uClibc 0.9.30.3 upgrade?)

Hi,

I am almost sure that setserial was building OK before uClibc upgrade to
0.9.30.3. Now I get:

Actual problem I see here is not with uClibc, but with setserial.c not including
stdlib.h. Due to my very limited time I can't provide fix now...
