kexec-tools-2.0.16 fails to compile here. There was a similar fix for -mindirect-branch but it seems -mfunction-return was forgotten. Reproducible: Always
The thunk-inline version was made to work with '-mcmodel=large', so instead of filter-flags it could replace it with thunk-inline like this: replace-flags -mfunction-return=thunk -mfunction-return=thunk-inline replace-flags -mindirect-branch=thunk -mindirect-branch=thunk-inline The only issue I see is that thunk-inline is slower than thunk. At least it would be nice if the ebuilds did not filter thunk-inline (only thunk instead of thunk*) since that compiles.
Problem is hidden in >=sys-apps/kexec-tools-2.0.19 which just ignores user-specified CFLAGS during relevant part of building: bug #692930.
