A few days ago, I tried to compile a gcc plugin with the toolchain from poky sdk.
It failed with errors about missing header files such as backend.h etc.
After investigation, I found that the problem was brought by a gcc patch:
0012-gcc-Fix-argument-list-too-long-error.patch (which is considered derived from the original patch)
- headers=`echo $(PLUGIN_HEADERS) $$(cd $(srcdir); echo *.h *.def) | tr ' ' '\012' | sort -u`; \
+ headers="$(sort $(PLUGIN_HEADERS) $$(cd $(srcdir); echo *.h *.def))"; \
It changes the commands of install-plugin, making the sorting taken effect before the shell globs.
Thus results in the header files under gcc $(srcdir) being not installed.
By checking log.do_install, we can find that the `headers=' statement to run is incorrect and will not work as expected:
headers="$(cd *.def) *.h ../../../../../../../work-shared/gcc-10.1.0-r0/gcc-10.1.0/gcc/../include/ansidecl.h ...
As the patch says,
"The PLUGIN_HEADERS is too long before sort, so the "echo" can't handle it, ..."
my suggestion is that we can simply take care of PLUGIN_HEADERS
using the original proposed sort.

This fixes the gcc patch as proposed as it does appear its been
broken over time.
