#253 CFLAGS for Solaris need PIC specified

[James C. McPherson]

I'm building GLEW on Solaris 11.2 using Solaris Studio 12.3. I found that until
-Kpic was added to the CFLAGS.EXTRA, errors such as this littered my screen:

ld: warning: relocation error: R_AMD64_PC32: file lib/libGLEW.so: symbol GLXEW_SGI_swap_control: displacement relocation applied to the symbol <unknown> at 0x88739: symbol GLXEW_SGI_swap_control is a copy relocated symbol

ld: warning: relocation error: R_AMD64_PC32: file lib/libGLEW.so: symbol glewXSwapIntervalSGI: displacement relocation applied to the symbol <unknown> at 0x814d3: symbol glewXSwapIntervalSGI is a copy relocated symbol

A similar change is needed for Makefile.solaris-gcc: -fPIC
