Call to undefined function posix_fpathconf() in default configure setting

[mumumu]

Description

The following code:

$ ./sapi/cli/php -r 'echo posix_fpathconf(0, POSIX_PC_LINK_MAX);'

Resulted in this output:

Fatal error: Uncaught Error: Call to undefined function posix_fpathconf() in Command line code:1
Stack trace:
#0 {main}
  thrown in Command line code on line 1

But I expected this output instead:

127
