[PATCH v4 0/2] sframe: Fix sframe handling when doing garbage collection

[claudiu.zissulescu-ianculescu@oracle.com]

From: Claudiu Zissulescu <claudiu.zissulescu-ianculescu@oracle.com>

Hello,
 
Please find a series of patches that fixes the removing of sframe
sections during garbage collection. This patch series fixes the
bugzilla issue PR ld/32769.

What is new:
 - Added a new test for checking the sframe relas when we GC.
 - sframe-gc-sections-* are checking if the full sframe dump is correct.

Observations:
 - ld: bfd: sframe: KEEP .sframe sections and support gc-sections is reviewd by Jens, included here for completion.

OK for mainline?
Claudiu
