selftests/rseq: Fix out-of-tree compilation
[ Upstream commit ef89d0545132d685f73da6f58b7e7fe002536f91 ]
Currently if you build with O=... the rseq tests don't build:
$ make O=$PWD/output -C tools/testing/selftests/ TARGETS=rseq
make: Entering directory '/linux/tools/testing/selftests'
...
make[1]: Entering directory '/linux/tools/testing/selftests/rseq'
gcc -O2 -Wall -g -I./ -I../../../../usr/include/ -L./ -Wl,-rpath=./ -shared -fPIC rseq.c -lpthread -o /linux/output/rseq/librseq.so
gcc -O2 -Wall -g -I./ -I../../../../usr/include/ -L./ -Wl,-rpath=./ basic_test.c -lpthread -lrseq -o /linux/output/rseq/basic_test
/usr/bin/ld: cannot find -lrseq
collect2: error: ld returned 1 exit status
This is because the library search path points to the source
directory, not the output.
We can fix it by changing the library search path to $(OUTPUT).
