RFR: 8179887 - Build failure with glibc >= 2.24: error: 'int readdir_r(DIR*, dirent*, dirent**)' is deprecated

[Michal Vala]

Hi,

following discussion "RFR: build pragma error with gcc 4.4.7"[1], I'm posting 
updated patch replacing deprecated readdir_r with readdir. Bug ID is JDK-8179887 
[2].

webrev: http://cr.openjdk.java.net/~andrew/8179887/webrev/

I'm asking for the review and eventually sponsorship.

Thanks!
