Build with meson + clang + sanitizer resulted in undefined reference

Hi!

Recently, I'm stumbled in such an easy task as build Postgres with clang and
sanitizer.

Usually, I use autotools to build Postgres something like this:
================================================================================
SRC="../postgres"
TRG="/tmp"

LINUX_CONFIGURE_FEATURES="
    --without-llvm
    --with-tcl --with-tclconfig=/usr/lib/tcl8.6/ --with-perl
    --with-python --with-gssapi --with-pam --with-ldap --with-selinux
    --with-systemd --with-uuid=ossp --with-libxml --with-libxslt --with-zstd
    --with-ssl=openssl
"

CC="ccache clang" CXX="ccache clang++" \
CFLAGS="-Og -ggdb -fno-sanitize-recover=all -fsanitize=alignment,undefined" \
CXXFLAGS="-Og -ggdb -fno-sanitize-recover=all -fsanitize=alignment,undefined" \
LDFALGS="-fsanitize=alignment,undefined" \
\
$SRC/configure \
    -C \
    --prefix=$TRG/"pgsql" \
    --enable-debug --enable-tap-tests --enable-depend --enable-cassert \
    --enable-injection-points --enable-nls \
    $LINUX_CONFIGURE_FEATURES

================================================================================

Then it compiles with no problems.

Now I exact the same, but with meson build.
================================================================================

And then upon build I've got overwhelmed by thousands of undefined reference errors.

Previously, I've got the same troubles on my old trusty 32-bit laptop on Debian.  But, there was no time to dig deeper in the problem 

at the time.  And now same for 64-bit Ubuntu.  The most common reason for such errors are not passing appropriate sanitizer 

flags to LDFLAGS, but this is not the case.  What could be the reason for this?  Am I doin' something wrong?

Exact the same sequence, but for GCC, works splendidly.
