Message:

Merge toolchain upgrade and related changes. Highlights:

• GCC 4.6, binutils 2.21
• change the default CROSS_PREFIX to /usr/local/cross to avoid ugly pollution in the /usr/local directory (closes #252)
• amd64: use a silly workaround to avoid possible GCC 4.6 bug (going to report to GCC's bugzilla)
• toolchain.sh now supports parallel toolchain build (i.e. all targets at once)
• improve linker scripts to support the newest compiler input sections
• remove unused variables and other various fixes for GCC 4.6 warnings (GCC 4.5.1 also passes compilation)
• unification of kernel memcpy() and memstr() functions (use compiler builtins whenever possible, keep plain C fallback implementations in a sepearate object file)

File:

• kernel/generic/include/lib/memfnc.h (moved) (moved from kernel/arch/ia64/include/memstr.h ) (3 diffs)
