# 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
Checking integrity... done (0 conflicting)
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@aarch64
devel/freebsd-gcc9@aarch64
devel/binutils@aarch64
