n2n @3.0: ld: -L must be immediately followed by a directory path (no space)

[barracuda156]

The build fails with gcc-4.2:

/usr/bin/gcc-4.2 -std=gnu99 -L/opt/local/libexec/openssl11/lib -L/opt/local/lib -Wl,-headerpad_max_install_names -arch ppc -pthread -L .  src/supernode.o libn2n.a   -ln2n -lcrypto -lzstd  -o src/supernode
ld: -L must be immediately followed by a directory path (no space)

With macports-gcc-11 it succeeds though:

macmini:~ svacchanda$ port -v installed n2n
The following ports are currently installed:
  n2n @3.0_0 (active) requested_variants='' platform='darwin 10' archs='ppc' date='2022-03-27T18:10:02+0800'

No other changes, only specified the compiler.

it’s erroring due to the space between the L and the period:

 -pthread -L .

not sure why that space is there, or why changing the compiler would matter (presumably either the space doesn't happen any more or the compiler doesn't care any more).

In 83a70b23320cad948651be7e50d7971b52e8af6a/macports-ports (master):

n2n: Remove space after -L and -I

Fixes build failure with gcc-4.2.
