Additional Information:
Perhaps due to this change:
https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=cd748a63ab1a7ae846175c532a3daab341c62690

Now bsearch is defined as macro, and the util-linux source:

   1839                         if (bsearch(&(struct pollfd){.fd = fd,}, local.iov_base,
   1840                                     nfds, sizeof(struct pollfd), pollfdcmp))
   1841                                 file->multiplexed = 1;

is now parhaps recognized as calling macro with 6 parameters due to comma...
