RFR: JDK-8042213: Freetype detection fails on Solaris sparcv9 when using devkit

[Tim Bell]

Hello Erik:

> Please review this small fix to freetype detection in configure. On 
> Solaris, libs are typically found in the "isadir" for 64bit builds. 
> This was only handled for amd64 for freetype. This patch makes it more 
> universal.

> Patch inline:

Looks good to me.
