With a trivial fix for PR 43538, this works. However, we then hit PR 59472.
Also, if instead of gold 1.11 (which works fine) I use GNU ld 2.24, I get
warnings:
/usr/bin/ld: error in /tmp/cc5iP5Yf.ltrans2.ltrans.o(.eh_frame); no
.eh_frame_hdr table will be created.
because of crtend.o.
The path is long... At least, I tried the result, and it does help for PR 59048
and does allow removing operator delete(0).
