You can set an override var for the configure run,
whose name is best determined like:

$ grep cv.*expl config.log
ac_cv_have_decl_frexpl=yes
ac_cv_have_decl_ldexpl=yes
gl_cv_func_frexpl_no_libm=yes
gl_cv_func_frexpl_works=yes
gl_cv_func_ldexpl_no_libm=yes
gl_cv_func_ldexpl_works=yes

However, since you have a simple enough test
it seems it would be better to incorporate that to
the gnulib check, so that all can benefit.
