"." does appear first. It does look like thumb is being built first though.

$ arm-elf-gcc -print-multi-lib
.;
thumb;@mthumb
interwork;@mthumb-interwork
pic;@fPIC
thumb/interwork;@mthumb@mthumb-interwork
thumb/pic;@mthumb@fPIC

Building the posix dir -- which I've added to arm-* for my own
purposes -- fails because targ-include, which provides sys/dirent.h,
doesn't exist yet.
