It's GNU Make and linker specific.
The default Makefile rule looks like:
$(CC) $(CFLAGS) $(LDFLAGS) $@ $^ $(LDLIBS)
When linking is done by gcc itself, no issue, but when it needs to be passed
to proper ld, only LDLIBS follows and then ld cannot know what libs to link
with.
More detail:
https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html
LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the linker,
‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable
instead.
LDLIBS
Library flags or names given to compilers when they are supposed to invoke the
linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to
LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS
variable.
https://lkml.org/lkml/2010/2/10/362
tools/perf: libraries must come after objects
Link order matters, use LDLIBS instead of LDFLAGS to properly link against
libnuma.

instead.
LDLIBS
Library flags or names given to compilers when they are supposed to invoke the
linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to
LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS
variable.
https://lkml.org/lkml/2010/2/10/362
tools/perf: libraries must come after objects
Link order matters, use LDLIBS instead of LDFLAGS to properly link against
libpthread.

It's GNU Make and linker specific.
The default Makefile rule looks like:
$(CC) $(CFLAGS) $(LDFLAGS) $@ $^ $(LDLIBS)
When linking is done by gcc itself, no issue, but when it needs to be passed
to proper ld, only LDLIBS follows and then ld cannot know what libs to link
with.
More detail:
https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html
LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the linker,
‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable
instead.

LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the linker,
‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable
instead.
LDLIBS
Library flags or names given to compilers when they are supposed to invoke the
linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to
LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS

Link order matters, use LDLIBS instead of LDFLAGS to properly link against

Sometimes "$(CROSS_COMPILE)gcc" is not enough: For instance, we need
to pass --sysroot to CC:
CC="aarch64-linaro-linux-gcc
--sysroot=/oe/build/tmp-lkft-glibc/work/hikey-linaro-linux/kselftests-mainline/4.19-r0/recipe-sysroot"

Denys, apologies for sending this patch as Fathi's. In our Git
repository [1] he's marked as author, probably as it got copied from
repo to repo.
Would you mind sending this patch yourself?
Thanks and greetings!
