| 3 | # Call Makefile to do the work, but for the install case, we need to | |
| 4 | # call Makefile for each arch separately, and create fat dylibs at the | |
| 5 | # end. This is because the comm page symbols are added as a special segment, | |
| 6 | # which the linker will not thin, so we have to build thin and combine. | |

| 14 | # For each arch, we setup the independent OBJROOT and DSTROOT, and adjust | |
| 15 | # the other flags. After all the archs are built, we ditto over one on | |
| 16 | # time (for the non-dylib files), and then call lipo to create fat files | |
| 17 | # for the three dylibs. | |
