[Buildroot] [PATCH 1/1] toolchain/toolchain-wrapper: fix gcc -v with relro

[Fabrice Fontaine]

rhash in version 1.4.0 with relro fails to build because gcc -v raises
the following build failure:

/data/buildroot-test/instance-1/output-1/host/mips64el-buildroot-linux-gnu/sysroot/soft-float/el/usr/lib64/Scrt1.o: In function `__start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status
Run result: 1

This buid failure is raised because the toolchain-wrapper calls gcc with
-Wl,-z,relro and as a result gcc wrongly assumes that some linking must
be done with -v

Fixes:
