Notes for chealpix - reproducible builds result

Version annotated: 3.30.0-2
Identified issues:
Identifier: randomness_in_fat_lto_objects
URL https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66305
Description Objects built with `gcc -flto -ffat-lto-objects` will contain random strings
in the form of `.gnu.lto_.inline.24c30dabb443e726`. They will change at
each build.
Temporary (?) solution: pass the full path of the source as the argument
to `-frandom-seed`.
