The above macros may contain references to shell variables.
The cause of this problem is usually that in a configure.ac or
configure.in file, there is some code like
FOO_DIR="\${bindir}"
AC_DEFINE_UNQUOTED(FOO_DIR, "\$FOO_DIR", [Directory where foo files go])
You can fix this by telling the original package author not to use
AC_DEFINE_UNQUOTED for directories. Instead, {he,she} should do
something like this:
# in configure.ac:
foodir="\${bindir}"
AC_SUBST(FOO_DIR)
# in the Makefile.am files (can be more than one):
AM_CPPFLAGS= -DFOO_DIR=\\"@FOO_DIR@\\"

http://www.gnu.org/software/autoconf/manual/html_node/Defining-Directories.html
If this check is wrong and the package really wants to have "\${" in the
macros, append the above filenames to the CHECK_HEADERS_SKIP variable in
the package Makefile.
