Hi,
   I manage to get Catalina on my laptop (pretty old nowadays) but I'm
pretty busy at the moment.

I looked at the log.
So, the error is

ld: building for Mac Catalyst, but linking in dylib built for macOS,
file '../../dblib/.libs/libsybdb.dylib' for architecture x86_64h

trying to link fisql which is an executable. This error is apparently
a mismatch of ABIs. A mismatch between a shared library (dylib) and
the executable.
The 2 parameters that seem to specify the target are -arch and -target.

The command for the executable is

clang -D_THREAD_SAFE -arch x86_64h -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk
-target x86_64-apple-ios13.0-macabi -Wdeclaration-after-statement
-arch x86_64h -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk
-target x86_64-apple-ios13.0-macabi -o .libs/fisql fisql.o terminal.o
edit.o handlers.o interrupt.o  ../../dblib/.libs/libsybdb.dylib
../../replacements/.libs/libreplacements.a -liconv

the one for the dylib is

clang -dynamiclib -Wl,-undefined -Wl,dynamic_lookup -o
.libs/libsybdb.5.dylib  .libs/dblib.o .libs/dbutil.o .libs/rpc.o
.libs/bcp.o .libs/xact.o .libs/dbpivot.o
-Wl,-force_load,../tds/.libs/libtds.a
-Wl,-force_load,../replacements/.libs/libreplacements.a  -liconv
-arch x86_64h -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk
-arch x86_64h -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk
  -install_name
/Users/niklas/Downloads/freetds-ios/work/catalyst/build_ios/freetds/x86_64h/lib/libsybdb.5.dylib
-compatibility_version 7 -current_version 7.0 -Wl,-single_module

one thing weird is that this last has no -target specified. Maybe is
this the issue?

I also noted that tdspool, another executable, is linked successfully
but the difference here is that tdspool links only convenience
libraries (basically static libraries).

I would suggest manually to try to rebuild the dylib, something like:
- build as you are doing
- move to src/dblib
- launch the command to compile libsybdb.5.dylib with the additional
"-target x86_64-apple-ios13.0-macabi"
- move back to src/apps/fisql
- launch the command to compile fisql (I think also make should work here)

All object files have both -arch and -target too.

Did you run autoreconf? Sometimes it's helpful as it replaces the
libtool provided which sometimes helps under some systems, something
like
- "autoreconf -vif"
- configure
- make

Regards,
  Frediano
