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 hpuxi-acc-64
-#
-# We define _POSIX_C_SOURCE to 199506L when using threads, therefore
-# we also need to redefine _HPUX_SOURCE.
-# From pthread(3t):
-#   Some documentation will recommend the use of -D_REENTRANT for
-#   compilation.  While this also functions properly, it is considered
-#   an obsolescent form.
-# See pthread(3t) for more details.
-#
-# From the "HP aC++ Online Programmer's Guide":
-#   When +DA2.0W is specified:
-#   * 64-bit SVR4 Executable and Linking Format (ELF) object files
-#     are generated for PA-RISC 2.0.
-#   * The preprocessor predefined macro, __LP64__ is defined.
-#   * The correct path for 64-bit system and language libraries is
-#     selected.
-#   When +DD32 is specified:
-#   * The size of an int, long, or pointer data type is 32-bits.
-#     The size of an int data type is 32-bits. The size of a long or
-#     pointer data type is 64-bits.
-#   * This is the default, currently equivalent to +DA1.1 architecture.
-#   When +DD64 is specified:
-#   * The size of an int data type is 32-bits. The size of a long or
-#     pointer data type is 64-bits.
-#   * This is currently equivalent to +DA2.OW architecture.
-#   * The preprocessor predefined macro, __LP64__ is defined.
-#   Using +DS to Specify Instruction Scheduling:
-#   * By default, the compiler performs scheduling tuned for the system
-#     on which you are compiling, or, if specified, tuned for the setting
-#     of the +DA option.
-#
-# From the online "C/HP-UX Reference Manual":
-#   -Aa
-#     Enables strict ANSI C compliance.
-#   -Ae
-#     Enables ANSI C compliance, HP value-added features (as described
-#     for +e option), and _HPUX_SOURCE name space macro. It is equivalent
-#     to -Aa +e -D_HPUX_SOURCE.
-#   +e
-#     Enables the following HP value added features while compiling in
-#     ANSI C mode: sized enum, long long, long pointers, compiler supplied
-#     defaults for missing arguments to intrinsic calls, and $ in identifier
-#     HP C extensions.
