Having HOMEBREW_PATCHELF_RB set in the ENV,
will conditionally install patchelf.rb gem,
use patchelf.rb in the above mentioned methods.
The installed vendored gems are listed in .gitignore
to maintain a clean state.
Some elf files (e.g. created by rust compiler) have INTERP header despite
their magic header denotes shared object instead of executable.
We should relocate the interpreter elf files as long as they have INTERP header.
This should fix the broken bottles for rust based formulae.
Some elf files like unittest files or memory dumps may not be completely
readable by readelf.
Readelf will fail after the following message:
readelf: Warning: possibly corrupt ELF header - it has a non-zero program header offset, but no program headers
This patches avoid these files when there is a non zero offset but no
program headers
