The strongswan configure.in uses the AC_LIB_PREFIX macro, which adds
--with-lib-prefix and --without-lib-prefix options, and which, by
default assumes that adding ${prefix}/lib to LDFLAGS and
${prefix}/include to CPPFLAGS is a good idea. Obviously, when
cross-compiling, it is definitely not a good idea.
In the specific case of strongswan, the result is that when testing if
the backtrace() function was available, the small C program was being
built and linked with -L/usr/lib. So when the host architecture and
target architecture are identical, it may find the backtrace()
function in the host C library, without looking at the target C
library:
configure:16457: /home/test/outputs/a637f916962b6136dd6dd4f4b9ff4e1cab568ef3/output/host/usr/bin/x86_64-unknown-linux-uclibc-gcc -o conftest -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -pipe -Os -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -L/usr/lib conftest.c >&5
/home/test/outputs/a637f916962b6136dd6dd4f4b9ff4e1cab568ef3/output/host/opt/ext-toolchain/bin/../lib/gcc/x86_64-unknown-linux-uclibc/4.6.3/../../../../x86_64-unknown-linux-uclibc/bin/ld: warning: libc.so.0, needed by /home/test/outputs/a637f916962b6136dd6dd4f4b9ff4e1cab568ef3/output/host/opt/ext-toolchain/bin/../lib/gcc/x86_64-unknown-linux-uclibc/4.6.3/../../../../x86_64-unknown-linux-uclibc/lib/../lib64/libgcc_s.so, may conflict with libc.so.6
Passing --without-lib-prefix prevents this default behavior from
happening, and no stupid value is added to CPPFLAGS or LDFLAGS.
