Subject: lib/nolibc: Adapt musl imported `signal.h` to nolibc
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=463d1c92745d3b6650f43a9a3becd2a7c2b87ccc;p=unikraft%2Funikraft.git

lib/nolibc: Adapt musl imported `signal.h` to nolibc

The replaced values of SIGRTMIN and SIGRTMAX are effectively
the return values of musl's __libc_current_sigrtmin() and
__libc_current_sigrtmax() defined in musl/src/signal/sigrtmin.c
and musl/src/signal/sigrtmax.c
