Standard options:
--help print this message
--prefix=PREFIX install in PREFIX [$prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[same as prefix]
--bindir=DIR user executables in DIR [EPREFIX/bin]

--sysroot=PREFIX prepend PREFIX to library/include paths []
--cc=CC use C compiler CC [$cc]
--extra-cflags= specify compiler flags [$CFLAGS]
--extra-ldflags= specify linker options []
--strip-binaries strip symbol tables from resulting binaries
--disable-static make libtcc.so instead of libtcc.a
--disable-rpath disable use of -rpath with the above
--with-libgcc use /lib/libgcc_s.so.1 instead of libtcc.a
--enable-mingw32 build windows version on linux with mingw32
--enable-cygwin build windows version on windows with cygwin
--enable-cross build cross compilers
--with-selinux use mmap for exec mem [needs writable /tmp]
--sysincludepaths=... specify system include paths, colon separated
--libpaths=... specify system library paths, colon separated
