I suppose you're trying to build gcc-2.95.2.

I don't know about IRIX 5.2, but in IRIX 5.3 I had to do some hacking
to get gcc compiled at all. I hope you also installed the GNU binutils?

Here is my build recipe for binutils-2.9.1 and gcc-2.95.2 on IRIX 5.3,
it might work on IRIX 5.2 as well. I installed gcc-2.95.2 for IRIX 5.3,
SunOS 4.1.4, IRIX 6.[2345] in the same directory, hence the --prefix and
--exec-prefix flags. The GNU make utility lives in /it/bin/gmake. I use
the SGI MipsPRO C compiler to bootstrap gcc.

set path = (  /usr/sbin /sbin /usr/bsd /usr/bin /bin /usr/bin/X11 )
setenv MAKE /it/bin/gmake
setenv CC /usr/bin/cc

untar binutils
cd binutils
configure --prefix=/usr/it/packages/gcc/gcc-2.95.2/install \
  --exec-prefix=/usr/it/packages/gcc/gcc-2.95.2/install/irix53 \
  --program-prefix=g
/it/bin/gmake
/it/bin/gmake/install

set path = ( /usr/it/packages/gcc/gcc-2.95.2/install/irix53/bin $path )
rehash
setenv LDFLAGS -L/usr/it/packages/gcc/gcc-2.95.2/install/irix53/lib
setenv AS /usr/it/packages/gcc/gcc-2.95.2/install/irix53/bin/gas
setenv LD /usr/it/packages/gcc/gcc-2.95.2/install/irix53/bin/gld

untar gcc
configure --prefix=/usr/it/packages/gcc/gcc-2.95.2/install \
  --exec-prefix=/usr/it/packages/gcc/gcc-2.95.2/install/irix53 \
  --enable-threads --enable-languages='c,c++,objc,f77'

Edit config.status, set all fork stuff to 'no'
Re-run configure:
configure --prefix=/usr/it/packages/gcc/gcc-2.95.2/install \
  --exec-prefix=/usr/it/packages/gcc/gcc-2.95.2/install/irix53 \
  --enable-threads --enable-languages='c,c++,objc,f77'

/it/bin/gmake CFLAGS='-O' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2' bootstrap-leanMake stops, edir ../../gcc-2.95.2/libiberty/pexecute.c, comment out
  #include <vfork.h>
/it/bin/gmake CFLAGS='-O' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2' bootstrap-lean(again)
/it/bin/gmake install

It works for me, YMMV.

Certainly. Installing a broken compiler doesn't work.

Depends. IRIX 5.2 is no longer maintained by SGI, so it has quite some
vulnerabilities. If you want to have those vulnerabilities fixed, you
should upgrade to IRIX 6.5. However, if you have a lot of software that
depends heavily on IRIX 5.2 (like dmedia stuff), you should stay with
IRIX 5.2. Gcc 2.95.2 compiles out-of-the box on IRIX 6.5...
