After557b9d4, libc_start_files and libc_main steps are performed one after another. It doesn't make sense, especially since some of the libcs (glibc, uClibc-ng) go to great lengths to first install start files in the first step, libc_start_files, only to remove them immediately in the second step, libc_main. Current build steps also break in the xtensa newlib configurations, as it needs to install the custom xtensa headers before building the libgcc and after557b9d4, the headers are not installed before libgcc is built in pass-1. Therefore, finish what557b9d4mentioned but did not do: move header installation into a new step, libc_headers, and combine libc_start_files and libc_main into a single step. This also allows to combine the core pass-1/pass-2 steps, to be done in a subsequent commit. Signed-off-by: Alexey Neyman <stilor@att.net>
