unistd: fix link error on Solaris 8

[Bruno Haible]

On Solaris 8, I'm seeing this link error:

g++      -o test-unistd-c++ test-unistd-c++.o ../gllib/libgnu.a  -lrt -lsocket 
Undefined                       first referenced
 symbol                             in file
eaccess                             ../gllib/libgnu.a(euidaccess.o)
ld: fatal: Symbol referencing errors. No output written to test-unistd-c++
collect2: ld returned 1 exit status
*** Error code 1

It's because eaccess() is defined in libgen on this platform.
This fixes it:
