# pkg which /usr/local/bin/aarch64-unknown-freebsd14.0-ld
/usr/local/bin/aarch64-unknown-freebsd14.0-ld was installed by package aarch64-binutils-2.33.1_4,1

# pkg delete aarch64-binutils

Deinstallation has been requested for the following 3 packages (of 0 packages in the universe):

Installed packages to be REMOVED:
        aarch64-binutils: 2.33.1_4,1
        aarch64-gcc6: 6.5.0_3
        aarch64-gcc9: 9.3.0_1

Number of packages to be removed: 3

The operation will free 278 MiB.

Proceed with deinstalling packages? [y/N]: N

So it exists because I built and installed:

devel/freebsd-gcc6_at_aarch64
devel/freebsd-gcc9_at_aarch64
devel/binutils_at_aarch64
