build-all.py - switch to dynamic_lookup

Browse Source 
1) `-undefined,suppress` is deprecated and linking is sending warnings about it and it seems to be superseded by `dynamic_lookup`
2) `-flat_namespace` is not compatible with GMP when building for intel, for some reason and results in horrible errors during linking:

Example error:
```
ld: branch8 out of range 366651 in ___gmpn_add_nc
