Compilation does not respect LDFLAGS

In Gentoo, we have an internal check, so we know, if the build systems does respect the CFLAGS and LDFLAGS set by user.
In this example, my *FLAGS are:
CFLAGS: -march=native -mfpmath=sse,387 -mtune=intel -O3 -frecord-gcc-switches -fomit-frame-pointer -malign-data=abi -mtls-dialect=gnu2 -pipe
LDFLAGS: -Wl,--as-needed -Wl,--defsym=__gentoo_check_ldflags__=0 -Wl,-O1 -Wl,--sort-common -Wl,-z,now
With mxml3, all is fine, but with mxml4, the checks fails, as LDFLAGS are not used the same as set by user.

That's probably because DSOFLAGS gets used when building a shared library instead of LDFLAGS. I can look at updating the configure script to use the LDFLAGS value if DSOFLAGS is not set...

Yes, you are right. I just tried and added DSOFLAGS=${LDFLAGS} and it worked for me.
