Compilation of ir fails because of wrong LDFLAGS and/or LIBRARIES

[KlausMu]

cd ir
make HOSTOS=LINUX

gives

[LINK]          ir
/usr/bin/ld: ../libs/Linux_x86_64/libflirc.a(hid.o): in function `hid_send_packet':
/home/kotzin/.buildkite-agent/builds/Linux-1/flirc-inc/sw-main/lib/libtransport/hid.c:144: undefined reference to `hid_write'
/usr/bin/ld: /home/kotzin/.buildkite-agent/builds/Linux-1/flirc-inc/sw-main/lib/libtransport/hid.c:150: undefined reference to `hid_error'
...

I think this is because of wrong LDFLAGS and/or LIBRARIES.

Don't know exactly where to fix this in Makefile or cross.mk

What is being called is

cc main.c -o ir -L. -Wl,--start-group -lhidapi-hidraw -lusb-1.0 -Wl,--end-group -lusb-1.0 -lflirc -lir -L../libs/Linux_x86_64 -Wall -g -std=c99 -I. -I../libs/include -Ideps/include

What should be called is

cc main.c -o ir -L. -Wl,--start-group -lhidapi-hidraw -lusb-1.0 -lusb-1.0 -lflirc -lir -Wl,--end-group -L../libs/Linux_x86_64 -Wall -g -std=c99 -I. -I../libs/include -Ideps/include

So the --start-group --end-group is wrong and needs to include all libs.
And -lusb-1.0 is used twice.
