Mac: update build.sh to hack around autotools problem

Browse source 
For reasons I cannot explain, running configure for libdivecomputer claims that
certain feature tests pass, even though those features demonstrably aren't
there. This is happening for two compiler warning flags (-Wrestrict &
-Wno-unused-but-set-variable) as well as the test for clock_gettime.

To work around this, we manually edit the config.h file and the created
Makefile before building libdivecomputer.

This happened on macOS 10.11.6 with clang-800.0.42.1 (part of Xcode 8.2.1).

Tangentially related to:
See #1263
