Subject: Makefile.example: simplify and make it configurable
X-Git-Tag: rc-8_17_0-1~378
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f6ddc1fc1e25ff8ea866f90942719af898d0ef0c;p=thirdparty%2Fcurl.git

Makefile.example: simplify and make it configurable

- build in a single step.

- allow overriding all variables:
  source, target, compiler, libpaths, libs, flags.

Example:
```shell
LIBS= LDFLAGS= SRC=altsvc.c make -f Makefile.example
```

Closes #18554
