-How to create a cross-compiler on LINUX (or any other supported build platform)
-for haiku (information is copied from haiku's README):
-
-Please chdir into haiku's base directory (the one where Jamrules and README live).
-
-If you want to build the default (legacy, 2.95.3) gcc, do this:
-
-  $ ./configure --build-cross-tools ../buildtools
-
-One of the last output lines should tell you that the tools have been built
-successfully.
-
-If you're not interested in binary compatibility (or want to build for the PowerPC architecture), you can build gcc5 instead by doing this:
-
-  $ ./configure --build-cross-tools <arch> ../buildtools
-
-Replace "<arch>" with either "x86" or "ppc", depending on which of the two
-architectures you want to build for.
