Not really. See my other post to this thread.

Nope. --enable-static is the default unless AC_DISABLE_STATIC is used
in configure.ac. You could stop building static libraries by passing
--disable-static, or adding AC_DISABLE_STATIC to configure.ac.
--{en,dis}able-static vs AC_{DIS,EN}ABLE_STATIC apply to what kind of
libtool libraries to build, and have no effect on how programs are
linked.

just LDFLAGS ^^^

If you leave libtest_LDFLAGS = -static and pass LDFLAGS=-all-static, you'll
end up running
libtool --mode=link -static -all-static ...
In that case, behaviour is undefined, you should pick just one of those options.

But would you be unhappy if libtool took -static to be the same as calling
cc -static and/or ld -static to link?
Cheers,
Gary.
