Multiple targets can be built yes.

Not sure you need to set these values in PKG_CONFIG_PATH.
At least /usr/lib/pkgconfig/ is already set in PKG_CONFIG_LIBDIR.
Let me rephrase the man page of pkg-config:
PKG_CONFIG_LIBDIR is the primary paths list
PKG_CONFIG_PATH is the secondary paths list

The standard paths for your 64-bit machine should be built-in
in your pkg-config.
The standard path for 32-bit is already set automatically
in devtools/test-meson-builds.sh.
Only additional specific paths should be set in a config file.
What is a config file? It is loaded by devtools/load-devel-config:
- /etc/dpdk/devel.config (system-wide)
- or ~/.config/dpdk/devel.config (user config)
- or .develconfig (project directory config)
Personally I set all my configs in ~/.config/dpdk/devel.config.
Note that the same file is used to configure multiple tools.
For each build, some variables are reset the variable DPDK_TARGET is set,
and the config file is sourced.
The typical values of DPDK_TARGET are:
- i386-pc-linux-gnu
- x86_64-pc-linux-gnu
- x86_64-w64-mingw32
- aarch64-linux-gnu
- powerpc64le-linux-gcc
TLDR, I assume you just want to set an additional 64-bit path,
so the config file should look like:
if [ "$DPDK_TARGET" = x86_64-pc-linux-gnu ] ; then
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib64/pkgconfig
fi
