In the MinGW version of iverilog-vpi (C version located in driver-vpi)
we must only look at the first word of the IVERILOG_VPI_CC definition.
A recent change to the configuration process made this equal to
"gcc -std=gnu99" which will not be found when looking for the
gcc executable. We nee to look for "<path>\\bin\\gcc.exe". This
patch modifies the driver to only use the first word when looking for
the compiler, but uses the full value when compiling.
Move the header files from includedir/verilog to .../iverilog
because the verilog name is a little too generic. The iverilog-vpi
command should handle the changes.
This configure option causes the installed commands to have
a suffix string that makes them distinct from other versions
that also have a suffix string. This allows for multiple
installed versions of Icarus Verilog.
Also, move installed C/C++ header files into a subdirectory of
their own under the target include directory, to make clearer
the purpose and source of those files.
