Add Solaris support in cmake build

Add SOLARIS cmake platform definition.
Add settings for QT_DEFAULT_MKSPEC so that qplatformdefs.h can be found.
Solaris has its gssapi symbols in libgss.
Solaris supports @ORIGIN.

Solaris ld does not support --dynamic-list needed for reduce relocations.
Make solaris fail the reduce relocation test.

getauxval is specific to GNU libc and some other libc implementations on
Linux but sys/auxv.h is not. The bootstrap uses sys/aux.h as the only
indication for getauxval. This breaks builds on Solaris, so only make
sys/auxv.h an indicator for getauxval on linux or glibc based systems.

Solaris uses X11 so add it to the X11_SUPPORTED list.

Solaris network libraries for sockets etc are in socket and nsl.
ifreq does not have a member ifr_ifindex on Solaris, it uses
ifr_index. Add test to check if ifr_index is a member of ifreq.
The first struct in the in_addr union on solaris is defined as four
uint8_t, therefore four arguments are needed for its initializer list.
