Description of problem:
Leak sanatizer build do not work because of missing liblsan_preinit.o

Version-Release number of selected component (if applicable):
gcc version 8.2.1 20180905 (Red Hat 8.2.1-3) (GCC)

How reproducible:
create a C++ binary, build for leak sanatizer, watch the build (linking) fail

Steps to Reproduce:
1. create a C++ program  
2. compile with -fsanitize=leak -fno-omit-frame-pointer
3. linking will fail, 
/opt/rh/devtoolset-8/root/usr/libexec/gcc/x86_64-redhat-linux/8/ld: cannot find liblsan_preinit.o: No such file or directory


Actual results:
no binary generated

Expected results:
a generated binary which I can execute and get leak sanitizer result

Additional info:
all packages of devtoolset 8 are installed, 
this is a Red Hat Enterprise Linux Developer Suite, 7.6 installation 
I guess the file liblsan_preinit.o should be part of devtoolset-8-gcc, 
like others, for example /opt/rh/devtoolset-8/root/usr/lib/gcc/x86_64-redhat-linux/8/32/libasan_preinit.o,
but it is not there
