            Bug ID: 1248071
           Summary: Increase ELFRESERVE constant from 3072 to 3104
           Product: Fedora
           Version: rawhide
         Component: golang
          Assignee: vbatts(a)redhat.com

Description of problem:
Etcd and kubernetes built in rawhide with debugging info support fails with the
following error:

ELFRESERVE too small: 3104 > 3072

Version-Release number of selected component (if applicable):
golang-1.4.99-4.1.5beta2.fc24.x86_64

How reproducible:
Always

Steps to Reproduce:
1. clone etcd repository
2. set with_debug macro to 1
3. build etcd for master branch

Actual results:
Etcd fails to build

Expected results:
Etcd does not fail to build

Additional info:
To support debugging info, each build is hacked by adding -B flag in -ldflags
string:
-B 0x$(head -c20 /dev/urandom|od -An -tx1|tr -d ' \n')

This increases header for 32bytes which is exactly difference between 3104 and
3072.

Setting the constant to 3104 fixes this issue.
