Some older versions of U-Boot, or custom versions (like forks for some
boards), fail to build with host-gcc 10+, because of redefined symbols:
HOSTLD scripts/dtc/dtc
/usr/bin/ld: scripts/dtc/dtc-parser.tab.o:(.bss+0x10): multiple definition
of `yylloc'; scripts/dtc/dtc-lexer.lex.o:(.bss+0x0): first defined here
collect2: error: ld returned 1 exit status
make[4]: *** [scripts/Makefile.host:106: scripts/dtc/dtc] E
Since this has been fixed in recent-ish versions, we can't use an
unconditionaly patch, so we must have a conditional patch. However, a
patch may not always apply to arbitrary U-Boot versions or forks.
Upstream just dropped that line altogether:
018921ee79
So, we use a little sed-grep combo to do the exact same change.
