Makefile: reorder linker flags in the git executable rule

The XL C compiler can fail due to mixing library path and object
file arguments, for example when linking git while building with
"gmake LDFLAGS=-L$prefix/lib".

Move the ALL_LDFLAGS variable expansion in the git executable rule
to be consistent with all the other linking rules, namely to have
LDFLAGS such as -L$where before the object files *.o being linked
together.
