summary:

gh-75371: reformat Makefile.pre.in to accommodate for empty FRAMEWORKALTINSTALLLAST (#107035)

in the case of an empty FRAMEWORKALTINSTALLLAST, this patch prevents leaving
an astray linebreak and two tabs in the resulting Makefile.

Before change:
```
.PHONY: commoninstall
commoninstall:  check-clean-src  \
		altbininstall libinstall inclinstall libainstall \
		sharedinstall altmaninstall \

```

After change (with empty FRAMEWORKALTINSTALLLAST):
```
.PHONY: commoninstall
commoninstall:  check-clean-src  \
		altbininstall libinstall inclinstall libainstall \
		sharedinstall altmaninstall
```

M Makefile.pre.in
