Bug description

When using the compiler-libs in a program and trying to compile several source codes I noticed some options to gcc accumulated from one compilation to the next, despite I've tried to cleaned as many global variables as I could, including via Asmlink.reset().

Problem seems to be that the aforementioned reset function does not clean lib_ccobjs or lib_ccopts.

A quick test suggest that cleaning those does fix my issue without introducing any bug I could notice.

These variables are reset by Bytelibrarian.reset and Bytelink.reset, so indeed it seems correct to reset them in asmcomp/ modules that set them. Would you care to submit a Pull Request?
