Comment:
If I look into the libtool script without the commit i get:
```
# The linker used to build libraries.
LD=${LD:=ld}
```
which allows the linker to be overridden by the environment. With the commit i get:
```
# The linker used to build libraries.
LD="ld"
```
which sets the linker unconditionally.

So the problematic part of the commit is probably:
```
-               # e.g. AR="armv7l-linux-gnueabihf-ar" becomes AR="${AR:=ar}"
-               vsed -i -e "s,\([A-Z]\+\)=\"${XBPS_CROSS_TRIPLET}\-\(.*\)\",\1=\$\{\1:=\2\},g" \
+               # e.g. AR="armv7l-linux-gnueabihf-ar" becomes AR="ar"
+               vsed -i -e "s,\([A-Z]\+\)=\"${XBPS_CROSS_TRIPLET}\-\(.*\)\",\1=\"\2\",g" \
```

I'll revert that part only and see if it still builds ok.
