Does this patch fix your issue?:

No, it did not fix the issue.
$ pkg-config --cflags yaml-0.1
$ pkg-config yaml-0.1 --libs
-L/buildarea/jma1/wr-19-0518/19.45/sysroots/aarch64-wrs-linux/usr/lib64
-lyaml
This issue happened in Yocto, After completing the SDK build and
installing it, use a new shell to source the environment and try to
build the helper scripts.
export
SDKTARGETSYSROOT=/buildarea/jma1/wr-19-0518/19.45/sysroots/aarch64-wrs-linux
export
PKG_CONFIG_PATH=$SDKTARGETSYSROOT/usr/lib64/pkgconfig:$SDKTARGETSYSROOT/usr/share/pkgconfig
If I install libyaml to a non-standard location
(/home/masahiro/foo), my pkg-config shows as follows:
masahiro@oscar:~$ pkg-config --cflags yaml-0.1
-I/home/masahiro/foo/include
masahiro@oscar:~$ pkg-config --libs yaml-0.1
-L/home/masahiro/foo/lib -lyaml
