linker_unload validate related issue (how to duplicate that?).

I've noted that validate is failing on Linux recently due to issue in 
linker_unload. As I've submitted some patch to this test case recently 
which fixes this on Solaris I'm kind of curious if I broke it or not. 
Anyway, strange thing is: when I configure ghc and run the test by 
(g)make TEST=linker_unload on both Linux and Solaris I get no failure. 
When I validate on Linux (validate is not working on Solaris yet), then 
I get failure in linker_unload:

Wrong exit code (expected 0 , actual 2 )

/bin/sh: 1: Syntax error: Unterminated quoted string
make[3]: *** [linker_unload] Error 2

*** unexpected failure for linker_unload(normal)

when I try to run:

cd testsuite
make TEST=linker_unload

inside this validation tree I again get no failure in this test:

=====> linker_unload(normal) 2522 of 4082 [0, 0, 0]
cd ./rts && $MAKE -s --no-print-directory linker_unload    </dev/null 
 > 2>

I've also noted that this test case fails on Solaris builders with 
strange error:

=====> linker_unload(normal) 170 of 4082 [0, 0, 1]
cd ./rts && $MAKE -s --no-print-directory linker_unload </dev/null 
 > 2>
Wrong exit code (expected 0 , actual 2 )
linker_unload: internal error: loadObj: can't read 
(GHC version 7.9.20140806 for i386_unknown_solaris2)
Please report this as a GHC bug:
gmake[3]: *** [linker_unload] Abort (core dumped)

So the question is: why validate fails and why builder fails on this 
particular test and why my common testing on both Solaris and Linux is 
not able to duplicate the issue? What's so different between validate 
and builders and between my common: perl boot; ./configure <some 
params>; gmake -j12; cd testsuite; gmake THREADS=12 fast
