Description of problem:
avr-libc fails to build from source for Fedora EPEL7 on RHELSA-7.2.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. On a RHELSA-7.2 host:
mock rebuild avr-libc-1.8.0-5.el7.src.rpm
Fails to build with the following error:
configure: error: cannot guess build type; you must specify one
builds without errors.
According to the spec file:
#autoreconf -fiv # required for aarch64 support, not needed since autotools 2.69+
however RHELSA-7.2 provides autoconf-2.69-11.el7, and the build still fails. If I uncomment that line:
autoreconf -fiv # required for aarch64 support, not needed since autotools 2.69+
the build completes successfully.
