RFR: JDK-8164304: JDK should build with Oracle Developer Studio

[Erik Joelsson]

This patch slightly adjusts the matching pattern which identifies the 
C/C++ compilers as Solaris Studio/Oracle Developer Studio so that the 
new output of 12.5 is also matched. Note that this only makes configure 
accept the new version as a valid compiler. The build dies almost 
immediately due to compilation errors.
