1Search target sysroot gcc version specific dirs with multilib.
2
3We install the gcc libraries (such as crtbegin.p) into
4<sysroot><libdir>/<target-sys>/5.2.0/
5which is a default search path for GCC (aka multi_suffix in the
6code below). <target-sys> is 'machine' in gcc's terminology. We use
7these directories so that multiple gcc versions could in theory
8co-exist on target.
9
10We only want to build one gcc-cross-canadian per arch and have this work
11for all multilibs. <target-sys> can be handled by mapping the multilib
12<target-sys> to the one used by gcc-cross-canadian, e.g. mips64-polkmllib32-linux
13is symlinked to by mips64-poky-linux.
14
15The default gcc search path in the target sysroot for a "lib64" mutlilib is:
16
17<sysroot>/lib32/mips64-poky-linux/5.2.0/
18<sysroot>/lib32/../lib64/
19<sysroot>/usr/lib32/mips64-poky-linux/5.2.0/
20<sysroot>/usr/lib32/../lib64/
21<sysroot>/lib32/
22<sysroot>/usr/lib32/
23
24which means that the lib32 crtbegin.o will be found and the lib64 ones
25will not which leads to compiler failures.
26
27This patch injects a multilib version of that path first so the lib64
28binaries can be found first. With this change the search path becomes:
29
30<sysroot>/lib32/../lib64/mips64-poky-linux/5.2.0/
31<sysroot>/lib32/mips64-poky-linux/5.2.0/
