egcs-980221, sunos4 bootstrap failure + patch

[Kaveh R. Ghazi]

	I had some trouble bootstrapping egcs-980221 on
sparc-sun-sunos4.1.3 because that platform contains a non-conforming
prototype of `free' in stdlib.h, and many new files are now including
stdlib.h whereas previously they did not. 

 > cc -c  -DIN_GCC    -g  -DHAVE_CONFIG_H     -I. -I. -I./config ./genattr.c
 > "./genattr.c", line 38: redeclaration of free
 > make[2]: *** [genattr.o] Error 1

	The following patch adds NEED_DECLARATION_FREE macros to protect
from this whereever I found it necessary for the bootstrap to succeed.

        * genattr.c: Wrap prototype of `free' in NEED_DECLARATION_FREE.
        * genattrtab.c: Likewise.
        * genconfig.c: Likewise.
        * genemit.c: Likewise.
        * genextract.c: Likewise.
        * genflags.c: Likewise.
        * genopinit.c: Likewise.
        * genoutput.c: Likewise.
        * genpeep.c: Likewise.
        * genrecog.c: Likewise.
        * tlink.c: Likewise.  Also wrap `getenv' in NEED_DECLARATION_GETENV.
