libgomp testsuite: Don't amend 'LD_LIBRARY_PATH' for system-provided HSA Runtime library
This is only active if GCC is 'configure'd with '--with-hsa-runtime=[...]' or
'--with-hsa-runtime-lib=[...]' -- which nobody really is doing, as far as I can
tell.
'libgomp/testsuite/lib/libgomp.exp:libgomp_init' states:
# For build-tree testing, also consider the library paths used for builing.
# For installed testing, we assume all that to be provided in the sysroot.
if { $blddir != "" } {
[...]
global hsa_runtime_lib
if { $hsa_runtime_lib != "" } {
append always_ld_library_path ":$hsa_runtime_lib"
}
}
However, the libgomp GCN plugin is unconditionally built against the
GCC-shipped 'include/hsa*.h' header files, and at run time does
'dlopen("libhsa-runtime64.so.1")', so there is no system-provided HSA Runtime
library "used for builing". It thus doesn't make sense to amend
'LD_LIBRARY_PATH' for system-provided HSA Runtime library.
libgomp/
* testsuite/lib/libgomp.exp (libgomp_init): Don't
'append always_ld_library_path ":$hsa_runtime_lib"'.
* testsuite/libgomp-test-support.exp.in (hsa_runtime_lib): Don't set.
