Yes and no ( see  below)

Based on configure command I expect native build. I cannot understand 
why is specified i686-pc-mingw32. May be in you environment native 
compiler is i686-pc-mingw32-gcc.exe and gcc.exe is another compiler.

More important to reported case is use of LD_LIBRARY_PATH. So many 
projects will set this environment variable but shared-path-variable is 
platform(os) dependent. On windows it is only PATH .

As xmlsec use libtool dl-library and this library use own path variable 
(LTDL_LIBRARY_PATH) and I prefer to use lt-variable in my linux->mingw 
cross-build environment:
     # set LTDL_LIBRARY_PATH so ltdl will find *.la files in build
     # dir instead installed and will load dll from build tree
     LTDL_LIBRARY_PATH="`winepath -w 
     LTDL_LIBRARY_PATH="`winepath -w \`pwd\`/src/gcrypt`;$LTDL_LIBRARY_PATH"
     LTDL_LIBRARY_PATH="`winepath -w 
     make check ...

I lack time to test with relative paths and with ':' as path-separator. 
If this work on windows may be xmlsec could be improved to set 
LTDL_LIBRARY_PATH instead LD_LIBRARY_PATH to allow test to be executed 
on more platforms.

Proposed change is to use following:
     for i in $(XMLSEC_CRYPTO_LIST) ; do \
         export LTDL_LIBRARY_PATH="src/$$i:$$LTDL_LIBRARY_PATH" ; \
     done && \
in Makefile.

Feedback is welcome .
