Subject: Revert "opkg: disable the use of vfork for the host build"
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=d0b88b606754cccb39b536dc921af268a1ef3ee8;p=oweals%2Fopenwrt.git

Revert "opkg: disable the use of vfork for the host build"

This reverts commit 02e3c718e9ad0c14aa3cf359ba2a4763e81df805.

Currently the vfork() code path in opkg is broken and relies on unsupported
ftello() / fseeko() operations on pipes - we need to restructure the code
before we can reconsider this approach.
