Perl on Solaris Sparc incorrectly adds -L/usr/lib/sparcv9 into ldflags and lddlflags

[vlmarek]

Perl incorrectly adds /usr/lib/sparcv9 to list of library search paths. If you do you may not be able to override a library from that path with library of your own.

At the moment perl compiled on solaris sparc shows:

$ perl -V | grep usr/lib/sparcv9
    ldflags =' -m64 -fstack-protector-strong -L/usr/lib/sparcv9 -L/usr/gnu/lib '
    libpth=/lib/64 /usr/lib/64 /usr/gcc/13/lib /usr/lib /usr/lib/sparcv9 /usr/gnu/lib /usr/ccs/lib
    libc=/usr/lib/sparcv9/libc.so
    lddlflags=' -shared -m64 -L/usr/lib/sparcv9 -L/usr/gnu/lib -fstack-protector-strong'

Both ldflags and lddlflags incorrectly add -L/usr/lib/sparcv9 to link command.

This can happen:

gcc ... -L/usr/lib/sparcv9 ... -Lmy_workspace/lib -lsnmp

will use libsnmp.so from /usr/lib/sparcv9 instead from my_workspace/lib as intended.

Please note that this is solaris specific change but for sparc only. X86 does not include such a change.

This is a workaround/fix I am going to include in Solaris Perl package:
