- After patching, RTGUI module will not be built.

The startupinfo does not have any visible effects on the building
process and some old Python version does not have it at all. So remove
it for the seek of simple.
Tested `scons -j4` in a dual core virtual machine.
Windows(tm) CreateProcess does not use the env passed to it to find the
executables. So we have to modify our own PATH to make Popen work. Also,
detect the cmd build-in commands and execute it directly.
Tested on MDK toolchain on RB4088 and the MSVS toolchain on simulator
BSP.
In SCons manual:
=================
In order to inform the C compiler about the repositories, SCons will
add appropriate -I flags to the compilation commands for each directory
in the $CPPPATH list. So if we add the current directory to the
construction environment $CPPPATH like so:
env = Environment(CPPPATH = ['.'])
env.Program('hello.c')
Repository('/usr/repository1')
Then re-executing SCons yields:
% scons -Q
cc -o hello.o -c -I. -I/usr/repository1 hello.c
cc -o hello hello.o
=================
The additional include directory is definitely not what we want. Just
remove the additional Repository line.
It adds the '--clang-analyzer' option that could invoke clang as the
static code checker. It is recommanded to work with 'scan-build' shipped
with Clang. For example, `scan-build scons --clang-analyzer`.
When --cscope option is given to Scons, it will generate a cscope
cross-reference database in current directory, which is useful in
Vim(and other cscope-aware text editors). For example, `scons -s
--cscope` will do nothing except generating the database. You can use
this option with other options together.
It is inspired by the `make cscope` of Linux.
The return type of SConscript is a subclass of UserList. We should use
extend to keep the depth of the list is always 1 when concatenate
SConscript return values. Thanks prife for making me realize that this
is really a problem.
