New Comment:
It has been a deliberate change to no longer support iconv(3)
implementations which do not set errno as of PHP 8.0.0[1], because
the fallback code was flawed, and such iconv(3) implementations
are not POSIX conformant anyway. Anyhow, this change will not be
reverted.
It is possible, though, that the detection of errno support is
flawed, or that something else with our configure scripts is not
quite right in this regard. However, without further information
(such as the respective part of config.log), we can't do anything
about this.

Tomas, could you please tell us what error is logged in the config.log?
As suggested by cmg, this is a problem of detection; but in my case (FreeBSD 10.2, with
"hand"-compiled GNU iconv 1.16 without pkgconfig), the detection program had no problem,
rather it was its compile env that lacked a -liconv.
So this could be circumvented by running an:
export LDFLAGS="$LDFLAGS -liconv"
before the configure.
I _think_ that, like you, I had no problem compiling a PHP 7 in the same environment (so this detect
failure would be a configure regression); but I cannot be certain.

I am also getting the same error.
Will it be fixed in the next version?

As of PHP 8.0.0, iconv implementation which do not support errno
(i.e. non POSIX conforming implementations) are no longer
supported. Either you glic iconv does not support errno, or that
support is wrongly detected.
Consider to install and use libiconv.

Description:
------------
I'm unable to compile PHP 8.0.0 with enabled iconv.
This is output from configure command:
checking for iconv support... yes
checking for iconv... yes
checking if iconv is glibc's... yes
checking if iconv supports errno... no
configure: error: iconv does not support errno
I tried compile PHP 7.4.13 with the same version of iconv (1.16), there everything is OK.
checking for iconv support... yes
checking for iconv... yes
checking if iconv is glibc's... yes
checking if iconv supports errno... yes
checking if iconv supports //IGNORE... no
