The program, axfer, was developed in userspace with glibc-2.28. This
userspace is mostly compliant to POSIX:2008 and some additional macros
for poll event are officially available. The glibc supports them as a
default since its v2.12 release. It will be failed to be compiled with
old glibc or the other libraries for C standard APIs.
One of the purpose of axfer is an better alternative of aplay. In a
point of the purpose, it's preferable to be compiled with the old
libraries.
This commit adds conditional macros to be compiled with libraries for
old compliance level of POSIX.
