Subject: fix missing errno from exec failure in posix_spawn
X-Git-Tag: v0.9.13~72
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=65d7aa4dfde9697b93d765f2f736e5f4a38bdfd5;p=oweals%2Fmusl.git

fix missing errno from exec failure in posix_spawn

failures prior to the exec attempt were reported correctly, but on
exec failure, the return value contained junk.
