make install fails with CHECK_SYMBOLS=no

[Diyou]

wasix-libc/Makefile

Lines 793 to 795 in 4048aab

	install: finish
	mkdir -p "$(INSTALL_DIR)"
	cp -r "$(SYSROOT)/lib" "$(SYSROOT)/share" "$(SYSROOT)/include" "$(INSTALL_DIR)"

This assumes an existing share folder which is only created here (which might be skipped):

wasix-libc/Makefile

Lines 706 to 710 in 4048aab

	check-symbols: startup_files libc
	#
	# Collect metadata on the sysroot and perform sanity checks.
	#
	mkdir -p "$(SYSROOT_SHARE)"

This results in a toolchain abort with:

cp: cannot stat '[...]/wasix-libc/sysroot/share': No such file or directory
