Reserving specified size of RUNPATH entry in the dynamic section during linking

[Jacob Kroon]

Hi,

As part of an effort to make binaries reproducible regardless of their
build path, I need to enforce the same size of the RUNPATH entry in the
dynamic section during linking, even though I don't fill it completely.
Is it possible to give some flag to gnu ld that allows me to set it to a
specific size ? Or is there a way to patch the elf file after linking,
so that the entry has a specified size ?

Regards
Jacob
