Currently, when rerunning the m4 configure script with caching enabled, this
output is appearing:
checking for intmax_t... (cached) yes
(cached) (cached) checking whether to enable assertions... no
I tracked both of those spurious messages to this. gl_ALLOCSA was calling
gl_FUNC_ALLOCA rather than AC_REQUIRE'ing it, so gl_FUNC_ALLOCA got expanded
twice in a row since the use of the allocsa module also pulls in the invocation
of gl_FUNC_ALLOCA from the alloca-opt module. Then gl_FUNC_ALLOCA was using a
cache variable, but without any useful messages.
OK to install?

* m4/alloca.m4 (gl_FUNC_ALLOCA): Use AC_CACHE_CHECK to avoid a
random "(cached)" in configure output.
* m4/allocsa.m4 (gl_ALLOCSA): Don't invoke macro already picked
up by the module dependency.
