Patch 050-build_fix.patch fixes the abscence of sha384-kdf.o from the
list of needed objetct files when FILS is selected without any other
option that will select the .o file.
While it is a bug waiting to be fixes upstream, it is not needed for
OpenWrt use case, because OWE already selects sha384-kdf.o, and FILS is
selected along with OWE.
