t1308-config-set.sh fails on current master (v2.13.1-449-g02a2850ad58e). 
The error is introduced by commit e2d90fd1c33a ("config.mak.uname: set 
FREAD_READS_DIRECTORIES for Linux and FreeBSD"). Reverting the commit 
results in a conflict, but the test works on the commit before, 
02912f477586.

Tested on

  Debian GNU/Linux 8.8 (jessie)
  Linux Mint 18 Sarah
