Specifically, that "lib" subdirectory would have to be populated like so:
lib
|-- engines
| |-- lib4758cca.so
| |-- ...
| `-- libubsec.so
|-- pkgconfig
| |-- libcrypto.pc
| |-- libssl.pc
| `-- openssl.pc
|-- libcrypto.a
|-- libcrypto.so -> libcrypto.so.1.0.0
|-- libcrypto.so.1.0.0
|-- libssl.a
|-- libssl.so -> libssl.so.1.0.0
`-- libssl.so.1.0.0
(If pkg-config is in $PATH, but lib/pkgconfig/openssl.pc is missing,
then httpd's configure will pick the "default" installation of OpenSSL,
and ignore the directory specified through --with-ssl.)

I tend to agree, and would be in favor of reverting r1358167. As long as
OpenSSL doesn't provide a Makefile target for creating the "lib"
subdirectory in the build tree, a workaround is to call configure with
suitable {CPP,LD}FLAGS, i.e.
CPPFLAGS=-I${openssl_build_dir}/include \
LDFLAGS=-L${openssl_build_dir} \
./configure ...
(when using the shared libssl/libcrypto libraries, adding
"-Wl,-R${openssl_build_dir}" or similar to LDFLAGS might make sense)
One problem with the current version of acinclude.m4 I noticed in the
meantime is that on OS X, the test in line 503
(https://svn.apache.org/viewvc/httpd/httpd/trunk/acinclude.m4?view=markup&pathrev=1358167#l503)
is true whenever --with-ssl is missing from the configure arguments (OS
X doesn't have /lib). configure will then add bogus "-L" strings to
SSL_LIBS and EXTRA_LDFLAGS in build/config_vars.mk... and this breaks
the link commands for the whole tree ("libtool: link: require no space
between `-L' and `-o'").
