build: centos/RHEL 7 ships with an older gcc and zlib
GCC 4.8.5 is the default system compiler on centos7/RHEL7. This version requires -std=c99 to enable c99 support. zlib 1.2.7 on centos7/rhel7 lacks uncompress2(). Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
