Allow user to add a directory component in the sys-root path.
Rename CT_DEBUG_INSTALL_DIR to CT_DEBUGROOT_DIR (to match CT_SYSROOT_DIR).
As a side effect, fix creating lib64->lib symlinks.

Original patch from Gentoo.

-= BEGIN original header =-

ARMV5 can use STRD and LDRD access instructions but these accesses need to be 

8 byte aligned. The dynamic linker's malloc needs to match this so structures

become 8 byte aligned to void unaligned accesses.
