Standardize the compiler output flag format across all RISC-V selftests by adding a space between '-o' and '$@'. Although '-o$@' is perfectly valid for GCC/Clang to parse, changing it to '-o $@' with a space aligns with the GNU official documentation conventions, improves readability by visually separating the flag from the target variable, and ensures consistency with other architectures. Currently, RISC-V selftests use '-o$@' (without space) in 13 instances across 6 Makefiles, while all other architectures consistently use '-o $@' (with space). This inconsistency makes RISC-V an outlier in the kernel's selftest infrastructure.

KSelfTest RISC-V
================
- These tests are riscv specific and so not built or run but just skipped
completely when env-variable ARCH is found to be different than 'riscv'.
- Holding true the above, RISC-V KSFT tests can be run within the
KSelfTest framework using standard Linux top-level-makefile targets:
$ make TARGETS=riscv kselftest-clean
$ make TARGETS=riscv kselftest
or
$ make -C tools/testing/selftests TARGETS=riscv \
INSTALL_PATH=<your-installation-path> install
or, alternatively, only specific riscv/ subtargets can be picked:
$ make -C tools/testing/selftests TARGETS=riscv RISCV_SUBTARGETS="mm vector" \
INSTALL_PATH=<your-installation-path> install
