[PATCH v2 00/25] linux-user/sparc: Implement rt signals

[Richard Henderson]

Supercedes: 20210425155749.896330-1-richard.henderson@linaro.org
("linux-user/sparc64: Implement signals")

This time, in the lead-up, merge the sparc and sparc64 directories.
Implement rt signals for sparc32 as well, since there are only a few
differences between the two.
