When processing the source files for an in-tree user TA (ta/*/user_ta.mk),
make sure not to insert a double slash in the object file path.
Fixes the following error:
$ make -s
$ make clean
CLEAN out/arm-plat-vexpress
rmdir: failed to remove 'out/arm-plat-vexpress/ta/avb': No such file or directory
Makefile:98: recipe for target 'clean' failed
make: *** [clean] Error 1
The error results from the fact that we have two kinds of object files in
the in-tree TAs:
- The object files built from ta/*/user_ta.mk. For AVB, we have
out/arm-plat-vexpress/ta/avb//entry.o (notice the repeated slash).
- The object files that correspond to "specified source files", i.e.,
constructed from $(spec-out-dir) and $(spec-srcs). For AVB we have
out/arm-plat-vexpress/ta/avb/user_ta_header.o.
When "make clean" creates the list of directories to be removed, it strips
the /filename part and keeps only the directory part, resulting in:
rmdir ... out/arm-plat-vexpress/ta/avb/ out/arm-plat-vexpress/ta/avb
Trying to remove the same directory twice: "No such file or directory".
