They have not been tested with Qt 5, not even once to make sure
that the mkspec passes the sanity check.
This removes for OSes:
HP-UX (running on PA-RISC -- Itanium still supported)
SGI IRIX
SCO Unix
Tru64 Unix
Unixware
And compilers:
IBM xlC (Visual Age C++)
HP aCC compiler (PA-RISC and Itanium)
PGCC, cxx and kcc on Linux
There were a couple more OSes detected in the configure script that were
lacking even the mkspec. Those have also been removed.
Of those, only hpuxi-acc and aix-xlc have been tested in the last 9
years, though only with Qt 4 and never tried with C++11 support. IRIX
was last tested over 10 years ago and PA-RISC is definitely not
supported due to its lack of atomic operations.
Support for HP-UXi and AIX is now only possible with GCC (assuming GCC
supports those). Support files for Oracle's Sun Studio compiler are left
behind, but its state is unknown.
