[PATCH 03/11] getdtablesize: Fix Android build

[Kevin Cernekee]

* m4/getdtablesize.m4: Add Android case to host OS check.  Recent NDK
versions have this symbol in the .so library (at least 32-bit
platforms) but are missing the declaration in the header file,
causing the m4 logic to guess incorrectly.
