This constant should be defined in limits.h. Define it in limits.h in the minimal libc, and use the definition found in newlib's includes. Values in newlib includes range from 1024 to 4096. The rationale is that all code should use the same value; having buffers specified with different sizes will lead to interoperability and out of bounds array writes.
