When configure has been run without errors, the package can be built with the make command. Some old packages still need the compilers to be specified on the make command line as in:
make CC="sh4-linux-gcc" CXX="sh4-linux-g++"
Other preprocessor symbols can be defined at compile time by adding them to the AM_CPPFLAGS variable on the make command line, for example:
make AM_CPPFLAGS="-DSTDC_HEADERS"
