Clean up mkspecs from old, unsupported and untested mkspecs

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.

-# qmake configuration for irix-cc-64
-#
-# From cc(1):
-#   -64
-#     Generates a 64-bit object. This defaults to -mips4 if -mips3 has
-#     not been specified.
-#   -LANG: ...
-#     The language feature option group controls the source language
-#     interpretation assumed by the compiler. The individual controls
-#     in this group are as follows:
-#       ansi-for-init-scope [ = ( ON|OFF ) ]
-#         Enables or disables the ANSI scoping rules for for-init
-#         declarations (the scope of the name declared extends to
-#         the end of the for statement). This enables the behavior
-#         that is required by the C++ standard. The default value
-#         is OFF, which is the ARM behavior (the scope of the name
-#         declared extends to the end of the block enclosing the for
-#         statement).
-#       bool [ = ( ON|OFF ) ]
-#         Enables or disables the predefined bool data type, along
-#         with the predefined values true and false. Use this option
-#         only to suppress this type in old code that defines bool
-#         itself.  Because this option changes the mangling of function
-#         names with bool parameters, all files comprising a program
-#         should be compiled with consistent options.
-#         Default is ON.
-#         The _BOOL feature macro can be used in #ifdefs to do conditional
-#         compilation based on whether or not this option is enabled.
-#       std
-#         Enables use of the standard C++ library and standard-
-#         conforming iostream library.  Specifying this flag also
-#         triggers other standard-conforming behavior, such as the
-#         new rules for the scope of for loop initializers.
