Details:

noticed on pkgsrc libtool 2.4.2 (patched)
as well as on master

libtool uses a construct in numerous places '${RM}r' where
if defined simply to the full path breaks miserably.

Here is a simple example (code source unimportant):

what works (this is after a --mode=compile stage):

richard@omnis:/home/richard/src/tlibtool$ ../libtool/libtool -v --tag=CXX
--mode=link g++ -shared -o libfoo.la -Wl,-h libfoo.so foo.lo
libtool: link: rm -fr  .libs/libfoo.a .libs/libfoo.la
libtool: link: ar cr .libs/libfoo.a .libs/foo.o 
libtool: link: ranlib .libs/libfoo.a
libtool: link: creating libfoo.la
libtool: link: ( cd ".libs" && rm -f "libfoo.la" && ln -s "../libfoo.la"
"libfoo.la" )

what doesn't:
richard@omnis:/home/richard/src/tlibtool$ RM=/usr/bin/rm ../libtool/libtool -v
--tag=CXX --mode=link g++ -shared -o libfoo.la -Wl,-h libfoo.so foo.lo
libtool: link: /usr/bin/rmr  .libs/libfoo.a .libs/libfoo.la
../libtool/libtool[1851]: eval[1]: /usr/bin/rmr: not found [No such file or
directory]
libtool: link: ar cr .libs/libfoo.a .libs/foo.o 
libtool: link: ranlib .libs/libfoo.a
libtool: link: creating libfoo.la
libtool: link: ( cd ".libs" && /usr/bin/rm "libfoo.la" && ln -s "../libfoo.la"
"libfoo.la" )


libtool should naturally test RM prior to using as thus.
