Subject: tools/nolibc: remove __nolibc_enosys() fallback from fork functions
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=fbd47de75502c63933016912325582309d72cd03;p=users%2Fjedix%2Flinux-maple.git

tools/nolibc: remove __nolibc_enosys() fallback from fork functions

All architectures have one of the real functions available.
The additional fallback to __nolibc_enosys() is superfluous.
