Comment:

 Replying to [comment:6 gk]:
 > So, I worked around that by building LLVM during the rust compilation
 (which make the whole process taking significantly more time) using that
 version in turn.

 I don't see LLVM being built in your patch. Is it done internally by the
 rust build system?

 The extracting of gcc and update of the PATH/LD_LIBRARY_PATH could be
 replaced by:
 {{{
 [% pc('gcc', 'var/setup', { compiler_tarfile =>
 c('input_files_by_name/gcc') }) %]
 }}}
 However it will also set hardened-cc links. Is it because the build
 doesn't work with hardened-cc that you didn't use it?

 For the `ln -s gcc cc` link, I am wondering if we should add it directly
 in `projects/gcc/build`, or if there are cases where we might not want
 this link.

 In `projects/tor/build`, I think the lines after the `IF c("var/linux") &&
 c("var/nightly")` can be indented.
