Description
As with other "final" output from the link-editor, kernel modules should not contain sections with the SHF_EXCLUDE flag set. These should only propagate to pure relocatable objects, which are presumed to be then input to further link-edits.

testing:
Test suite additions, illumos build and boot, building a given kernel object with clang (I picked one which happened to work) and made sure the SHF_EXCLUDE sections didn't make it through. Building libld with -Winline and making sure I didn't introduce anything new for andyf to fix. Toomas also built in his clang workspace and found it to be better.
