--- Comment #1 from Achim <Stromeko at nexgo dot de> ---
AFter a few false starts since it seems one really needs to freshly configure
and compile the whole thing each time this got bisected to:
https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=014a602b86f08de96fc80ef3f96a87db6cccad56
Why and how this produces the effect I've reported is a massive head-scratcher,
but I've confirmed that with this patch reverted 2.41 does not only link as
fast as 2.40 again, it is actually faster:
2.41re: 10.494u 1.370s 0:17.01 69.7% 0+0k 0+0io 1904230pf+0w
