bug#36762: libtool.m4 bug (spaces detection in compiler's output after -L/-R)

[Thomas Jahns]

Hi,

since it might take too long until a libtool release for some, I'll 
contribute the m4 code to patch the bug from autoconf:

m4_if(m4_cmp(m4_version_compare(LT_PACKAGE_VERSION,[2.4.6]),1),-1,
     [m4_pushdef([_LT_SYS_HIDDEN_LIBDEPS],m4_bpatsubst(m4_dquote(
        m4_defn([_LT_SYS_HIDDEN_LIBDEPS])),[test x-\([LR]\) = "\$p"],
          [test x-\1 = x"$p"]))])dnl
LT_INIT
m4_if(m4_cmp(m4_version_compare(LT_PACKAGE_VERSION,[2.4.6]),1),-1,
  [m4_popdef([_LT_SYS_HIDDEN_LIBDEPS])])dnl

Regards, Thomas
