From d2b14f02fbf6b8420abb4c77870d64df596fc0e9 Mon Sep 17 00:00:00 2001

Subject: [PATCH] build: fix pkg-config output path
When building the tarball from crates.io rather than from the git
repository, the target directory for the pkg-config file doesn't exist.
Note that when explicitly passing the --target option to cargo, this
changes the output directory from "target/<profile>/quiche.pc" (e.g.
"target/debug/quiche.pc") to "target/<target>/<profile>/quiche.pc" (e.g.
"target/x86_64-unknown-linux-gnu/debug).
Fixes #1142.
