[Buildroot] [PATCH] pv: support ccache builds

[Yann E. MORIN <yann.morin.1998@free.fr>]

Andrew, All,

On 2013-11-15 14:28 -0600, Andrew Ruder spake thusly:
> When using ccache TARGET_CC is something like
>     ccache gcc
> 
> This causes problems in the pv build which attempts to
> override LD because the command ends up being
>     make [...] LD=/tools/ccache /tools/gcc LDFLAGS="[...]
> 
> As a result, during the build phase it attempts to build
> /tools/gcc which succeeds by doing nothing:
>     make[1]: Nothing to be done for `/tools/gcc'.
> 
> and during the install phase you get the real build which
> errors out on the LD error this snippet was attempting to
> fix:
>     ld -r -o src/library.o src/library/getopt.o \
>         src/library/gettext.o
>     ld: src/library/gettext.o: Relocations in generic ELF \
>         (EM: 40)
>     src/library/gettext.o: error adding symbols: File in \
>         wrong format
