package/binutils: fix assertion in 2.29 xtensa ld

Section sorting code in xtensa ld was incorrectly cleaned up in release
2.29, resulting in the following assertion when --sort-section,alignment
option is used:

  BFD (GNU Binutils) 2.29 assertion fail elf32-xtensa.c:3965

Backport the fix that restores original section sorting.

+Subject: [PATCH] xtensa: ld: restore old section sorting behavior
+
+With the recent change 535b785fb0c9 ("Don't compare boolean values
+against TRUE or FALSE") the following assertion is observed when
+linking with --sort-section,alignment option:
+
+  BFD (GNU Binutils) 2.29 assertion fail elf32-xtensa.c:3965
+
+It appears that xtensa linker only supported sorting sections by name,
+and the code that checks for the section sorting type in
+ld/emultempl/xtensaelf.em was not updated in the change bcaa7b3eb957
+("ld/"), that replaced boolean wildcard_spec::sorted with enumeration.
+
+Restore the original behavior of the section sorting code.
+

+	* emultempl/xtensaelf.em
+	(xtensa_wild_group_interleave_callback): Only check for by_name
+	sorting.
