Building `bin2pat` and `pat2yara` crashes clang on macOS 10.6

An attempt to build retdec on macOS 10.6 via MacPorts works well with two exceptions: `pat2yara` and `bin2pat`.

Both tools is crashed clang-11 like this:

if I run `ld` in `gdb` I see that it crashed on parsing some static libraries:
```

```
and if I try to ping point a library which cause a crash, I'll find that `../../deps/install/yaramod/lib/libyaramod.a` cause such crash.

Anyway, disabling build of this two subprojects are enough.

Start with the CMake build of bin2pat and pat2yara on macOS 10.6, using the reported clang-11 linker command and the libyaramod.a archive identified in the report. Reproduce the ld crash under gdb and determine whether the two subprojects can build successfully or must be disabled; done means the affected build no longer crashes and the supported workaround is documented.
