Fix a problem with the libatomic testsuite using a method to determine
the compiler to use resulting in the tool being different from one the
library has been built with, and causing a catastrophic failure from the
lack of a suitable `--sysroot=' option where the `--with-build-sysroot='
configuration option has been used to build the compiler resulting in
the inability to link executables.
Address this problem by passing the `--tool_exec' option to `runtest'
via $(AM_RUNTESTFLAGS) with $(CC) as the argument, which will have all
the required options set for the target compiler to build executables in
the environment configured, removing failures like:
.../bin/riscv64-linux-gnu-ld: cannot find crt1.o: No such file or directory
.../bin/riscv64-linux-gnu-ld: cannot find -lm
collect2: error: ld returned 1 exit status
compiler exited with status 1
FAIL: libatomic.c/atomic-compare-exchange-1.c (test for excess errors)
Excess errors:
.../bin/riscv64-linux-gnu-ld: cannot find crt1.o: No such file or directory
.../bin/riscv64-linux-gnu-ld: cannot find -lm
UNRESOLVED: libatomic.c/atomic-compare-exchange-1.c compilation failed to
produce executable
and bringing overall test results for the `riscv64-linux-gnu' target
(here with the `x86_64-linux-gnu' host and RISC-V QEMU in the Linux user
emulation mode as the target board) from:
=== libatomic Summary ===
# of unexpected failures 27
# of unresolved testcases 27
to:
=== libatomic Summary ===
# of expected passes 54
libatomic/
* testsuite/Makefile.am (AM_RUNTESTFLAGS): New variable.
* testsuite/Makefile.in: Regenerate.

Changes from v1:
- Remove testsuite/libatomic-test-support.exp.in and the associated
changes.
- Pass $(CC) via `--tool_exec' in $(AM_RUNTESTFLAGS).
