Add configuration of include subdirectories

Browse Source 
Add the possibility to search headers in several subdirectories of
/usr/local/include and /usr/include. A possible use case would be for
tcc to search for headers in /usr/local/include/x86_64-linux-gnu,
/usr/local/include, /usr/include/x86_64-linux-gnu and /usr/include in
turn.
