Upgrading build system to new NetBSD revision The tested targets are the followgin ones: * tools * distribution * sets * release The remaining NetBSD targets have not been disabled nor tested *at all*. Try them at your own risk, they may reboot the earth. For all compliant Makefiles, objects and generated files are put in MAKEOBJDIR, which means you can now keep objects between two branch switching. Same for DESTDIR, please refer to build.sh options. Regarding new or modifications of Makefiles a few things: * Read share/mk/bsd.README * If you add a subdirectory, add a Makefile in it, and have it called by the parent through the SUBDIR variable. * Do not add arbitrary inclusion which crosses to another branch of the hierarchy; If you can't do without it, put a comment on why. If possible, do not use inclusion at all. * Use as much as possible the infrastructure, it is here to make life easier, do not fight it. Sets and package are now used to track files. We have one set called "minix", composed of one package called "minix-sys"

# $NetBSD: bsd.gcc.mk,v 1.4 2012/07/19 19:42:45 christos Exp $
build shared versions of libraries building defaults to off until clang is updated. current clang does not handle -shared, necessary to change the ld invocation to build shared libraries properly. a new clang should be installed and MKPIC defaults to no unless the newer clang is detected. changes: . mainly small imports of a Makefile or two and small fixes (turning things back on that were turned off in Makefiles) . e.g.: dynamic librefuse now depends on dynamic libpuffs, so libpuffs has to be built dynamically too and a make dependency barrier is needed in lib/Makefile . all library objects now have a PIC (for .so) and non-PIC version, so everything is built twice. . generate PIC versions of the compat (un-RENAMEd) jump files, include function type annotation in generated assembly . build progs with -static by default for now . also build ld.elf_so . also import NetBSD ldd

Enable optional GCC install and GCC improvements -By adding MKGCC=yes and MKGCCCMDS=yes on the make commandline it is now possible to compile and install GCC on the system. Before doing this, if you are not using the build.sh script, you will need to call the fetch scripts in order to retrieve the sources of GCC and its dependencies. -Reduce difference with NetBSD share/mk Move Minix-specific parameters from bsd.gcc.mk to bsd.own.mk, which is anyway patched, so that bsd.gcc.mk is now aligned on the NetBSD version. -Clean libraries dependencies, compiles stdc++ only if gcc is also compiled (it is part of the gcc sources) -Correct minix.h header sequence, cleanup spec headers. -Fix cross-compilation from a 32bit host targeting MINIX/arm Change-Id: I1b234af18eed4ab5675188244e931b2a2b7bd943
