Using the test case from the above issue, with the fix applied:

+ gcc 10, 32
ld: warning: dynamic library found on default search path (/usr/lib): libmtmalloc.so
collect2: error: ld returned 1 exit status

+ gcc 10, 64
ld: warning: dynamic library found on default search path (/usr/lib/amd64): libmtmalloc.so
collect2: error: ld returned 1 exit status

This seems entirely reasonable. Did you run the any of the tests that this may affect?

Not yet, but I have run a full gate build with a patched gcc7 and run wsdiff (which was clean apart from the usual suspects)

I've run the testsuite against this gcc7 branch (with both pending PRs applied):

I'm going to run it again without these two patches applied for comparison.
