cargo-asm doesn't always recompile if a file is changed

[fogti]

I have a project, and I tried comparing the assembler output between different releases/tags, but a simple git checkout wasn't enough to invoke a recompilation.

I switched to the following commands, which work (but is a bit too much brute force):

VER=v0.5.0 # next invocation was with VER=v0.5.1
git checkout "$VER" && \
  cargo clean && \
  cargo test && \
  cargo asm indented_blocks::parse_nested_blocks &> "../ib_pnb_$VER.S"
unset VER

The following should've worked as well, but didn't:

VER=v0.5.0
git checkout "$VER" && cargo asm indented_blocks::parse_nested_blocks &> "../ib_pnb_$VER.S"
unset VER

This might be easier to check just using line numbers, which should be different between v0.5.0 and v0.5.1 (at least on x86_64).
