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.
